Besides, removed redundant space before colon.

CHOP-238 Fix to bug introduced by http://hg.secondlife.com/viewer-beta/changeset/4072bd5389b2 Reviewed by Brad

STORM-687 FIXED Applied floater transparency to snapshot preview texture (unless the floater is focused, see STORM-676 to know why).

STORM-677 ADDITIONAL_FIX Force textures inside texture picker to be 100% opaque while the control is in a focused floater.

Besides, made LLFloater handle opacity more like other controls do.

DN-217 Changing between View Display Names on and off during a conference call session put viewer in a state where last name resident was shown in viewer everywhere for user in conference call with last name resident.

Bubble chat color picker now sets the background color for the name tag and bubble chat. Label for the color picker changed to "Bubble chat background"
Removed unused "BackgroundChatColor" setting, using "NameTagBackground" instead.

Added additional check to prevent infinite loop.
Blind fix since we have no repro.

- Deleted unnecessary draw() method that didn't call base LLFloater::draw() method.

- Deleted custom images of floater to use default

Comments on the mercurial bug tracker indicate that this bug is likely to
recur, so we work around it in viewer_manifest.py now.

Attempted fix for CHOP-223: fixed executable permissions on update_install script for mac and linux.

- Added parameter to the button that defines which transparency value should be used: value of drawing context or transparency value of a its parent (in our case this parent is floater)

STORM-688 FIXED Sidebar becomes semitransparent if dock semitransparent side panel back to the Sidebar

- Before docking the tab back to the sidetray, set floater's children to non-transparent state

- After detaching tab from the sidetray there is no need to set manually floater's children transparency. It happens automatically when floater gets focus.

Enabled the floater's background icons obey floater transparency.

STORM-698 FIXED Icon control can now respect floater transparency (if its "use_draw_context_alpha" param set to false).

STORM-498 FIXED reshaping dockable floater to ensure there is some vertical space between a floater and a control to which it is docked.

STORM-557 FIXED Update the "add/remove friend" buttons in the nearby/recent people panels whenever our friend list changes.

STORM-677 FIXED Made texture picker control transparent if the floater it resides in is transparent.

Also added transparency support to the texture picker floater.

STORM-530 FIXED Combobox drop down menu appears upon 'Down Arrow' key press even if last combobox item is selected.

STORM-344 FIXED Fixed Speak button label shrinking when bottom bar has enough space for displaying full Speak label.

Bug was caused by counting only width added by last resize as usable for Speak button extending, so widening viewer window by few pixels many times when Speak is shrink would never let it expand regardless of available space.

- Added check for possible chiclet panel shrinking width- cause spare space goes to it when extending. If there is enough space to give from chiclets to Speak, Speak is extended.

STORM-667 FIXED Default name tag color changed to white to increase contrast with default dark background.
