Modified code in indicated changeset to correct problem after consulting with
 Leyla Linden who sugested the orginal change. This fix will convert the Legacy
 name to a user name id not useing Display Names.

STORM-189 FIXED insufficient spacing between controls and truncations in IT, NL, PL and PT locales in Build Tools floater.

Added opaque water default settings to Linux featuretable.

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.

STORM-316 FIXED Added an item to inventory gear menu to control "Sort System Folders to Top" option (was always "true").
Changed inventory gear menu sort items - now they have check marks on the left.
Made inventory sort options persist across sessions.

- Added control_names for the "Show Advanced Menu" and "QAMode" checkboxes

STORM-589 FIXED Add a Preference that allows users to display the grid selection drop-down on the login screen

- Added a control_name for the "Show Grid Selection at login" checkbox

- Added a control_name for the "AllowMultipleViewers" checkbox

Previously name substitutions were broken, so "[FIRST] [LAST]" was displayed instead of avatar name.
Some of the affected notifications:
* avatar went online/offline notification
* object return notification
* calling card offer
* script dialog
* auto-unmute notification.
See the diff for more details.

The fixes apply to all locales but English (which is already correct).

Besides, I fixed calling card offer notification to display avatar name correctly. It was broken even in English.

 after loss during cleanup of preferences.
