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.

Fixed bug EXT-6337 (Changing maturity settings in preferences floater only works on first floater spawn when account is not age verified).

Added static member functions to LLViewerMedia: clearAllCookies(), clearAllCaches(), setCookiesEnabled(), and setProxyConfig().  These iterate through all loaded instances and send appropriate messages.

Also added a hack to clearAllCookies() to delete cookie files for all accounts, which should serve until we centralize cookie storage.

Made LLViewerMedia set the proxy config properly when creating new instances.  Callum is adding code to do something similar with the cookies enabled flag in a separate commit.

Removed get_web_media from llfloaterpreference.cpp and reworked everything that used it to use the new LLViewerMedia functions instead.
