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.

- Changed actions happening when minus or plus are held- now onSliderValueChanged() is not used for zoom via buttons. Zooming in and out now happens as it did
in 1.23 in LLJoystickCameraZoom::onHeldDown(), but only "Zoom in slow" and Zoom out slow" were borrowed from there, because fast versions are not needed- they do not happen in 1.23.

- Removed LLJoystickCameraZoom class, because it's not used anywhere. If need for it ever rises, it can be easily restored.

Fix:
- Save the UUID of a newly created wearable to start editing it right after it gets worn.
  This approach replaces a temporary hack that invoked the editing panel whenever an item gets worn
  (if the Appearance SP is opened at the time).
  The hack only happened to work sometimes because the editing panel failed to open.

Other changes:
- Removed a check for inventory item completeness from LLAgentWearables::editWearable().
  because the check often fails and doesn't appear to be needed at all.
- Added warning messages to LLAgentWearables::editWearable() so that it's easier to debug.
- Replaced duplicated code in LLPanelOutfitEdit::onEditWearableClicked() with a call to gAgentWearables.editWearable().

EXT-7631 FIXED Bad location of Empty Lost and Found option will lead to Critical Inventory loss by Residents

Separated Lost&Found from EmptyTrash as specified in EXT design decision.

Going through and cleaning up any todos that have "Seraph" attached to it.  In this case, did some header file cleanup of llinventorymodelbackgroundfetch and moved some functions protected/const/etc.

Reduced LowResTextures timeout from 3 to 2 minutes.

Also removes some redundant code, and registers UI callbacks for use from XUI.
