STORM-513 FIXED "Allow media to auto - play" check-box is enable after Media check-box was unchecked

- Disabling "Allow Media to auto play" check box only when both "Streaming Music" and "Media" are unchecked

STORM-34 ADDITIONAL_FIX Made saving favorites in file per-account preference instead of per-machine.

- Made changes in code of floater preferences and panel login that were required because of turning the setting per-account.

- Added new method to LLFloaterPreference that looks for current user's record in saved favorites file and removes it.

STORM-584 ADDITIONAL FIX When the user sets the opacity for the name tag the selected opacity is shown in the color swatch to the left.
Fixed color swatch label and tooltip.
Added toolltip to opacity slider.

STORM-34 FIXED Saving of user's favorites into file and showing them in "Start at" combobox on login screen was implemented.


Implementation details:

- File is saved on exit from viewer and not immediately on changes as was written in spec. It is done to make this file consistent with favorites order: order of favorites is saved on exit,
so if favorites info is saved in other moment earlier, crashing viewer or other unexpected way of finishing its work (i.e. via Windows task bar) would cause inconsistence between favorites order
saved per account and one from this new file.

- File is saved in user_settings\stored_favorites.xml.

- If you uncheck the option in Preferences and press OK, the file gets immediately deleted (according to spec).


Issues that require further changes:

- Currently only favorites of last logged in user are shown in login screen. Showing favorites of multiple users will be implemented later when design for it is approved by Esbee.

- Preference is now global for all users, because design states it may be changed before login, and we don't have account info at the moment. But it doesn't seem to be a good idea, so changes in design are needed.

- Currently the way of retrieving SLURLs needs optimization in a separate ticket.

More detailed design approved by Esbee is needed to develop it further, perhaps in new tickets.

The warning is shown only once (until the preferences floater is reopened).

STORM-576 FIXED Hooked up code to preference that allows users to enable double-click to teleport or use auto-pilot.

- Added dirty flag that is set true when user changes checkbox or chooses one of radiobuttons connected to double-click action. No change of user settings happens on this commit, because user may press cancel or close floater. If user presses OK, and flag is true, user changes are applied to settings.
If user clicks cancel or closes floater, controls are reverted to the state they were before changes, using settings to determine it.

- Removed double-click action menu items and code that handled them to avoid functionality duplication and synchronization problems.

fixed logic so that ignore consistently means *don't show* the notification
the ignore settings still store "show the notification if true" values

branch : storm-102

Changes:
- The line editor is now scrollable.
- Its value is duplicated in the tool-tip.

Technical notes:
If you set the "enabled" param of a line editor to "false", that will disable text selection in the widget.
However, if a line editor is initially enabled and then gets disabled with setEnabled(FALSE), it will remain selectable.
It looks like bug, but I'm not going to fix it now to not introduce issues like this one.
Instead, I'm applying to workaround which is to enable the widget initially and disable later, thus keeping it read-only but selectable.

popup blocking notifications now handled in all web_browser instances, not just llfloatermediabrowser

Removed obsolete XUI files:

floater_activeim.xml
floater_customize.xml
floater_device_settings.xml
floater_first_time_tip.xml
floater_im.xml
floater_my_friends.xml
floater_outfit_save_as.xml
floater_preview_classified.xml
floater_preview_event.xml
floater_preview_gesture_info.xml
floater_preview_gesture_shortcut.xml
floater_preview_gesture_steps.xml
floater_statistics.xml
floater_wearable_save_as.xml
panel_audio_device.xml
panel_friends.xml
panel_groups.xml
panel_nearby_chat.xml
panel_online_status.xml
panel_region_general_layout.xml

Killed obsolete LLFloaterVoiceDeviceSettings class, and moved LLPanelVoiceDeviceSettings into its own appropriately named files.

back-out the back-out for this branch.  yay.

Backing out this merge that I pushed (prematurely) to the wrong place.

EXT-6655 Fixed Made the default busy message repsonse localizable with already existing account settings

- The root of busy response problem is that this text is located in non-localizable xml and, to make things worse, may be changed by user. So usual translation approach is little help here. So busy response was set the following way(EXT-5885)- on first run, string was written there from strings xml and was never changed later without direct user actions. So after changin locale message always remained the same.

- To make this string localize each time locale is changed and if it is the same as default message, new setting was added- BusyResponseChanged which is TRUE if user's busy message differ's from default. If it is true, we do nothing when locale changes, otherwise we set default message from current locale as user's busy message.

- Old transitional code from DEV-24146 was removed in this diff including unnecessary "BusyModeResponse2" setting(it is not needed because we'll anyway have to set busy message to default after first run of viewer after this fix and now busy response will be stored in "BusyModeResponse").

Warning! If user modified busy response message before this fix, it will be reset to default after first postfix run.
