Moved type casts from protected base classes to derived LLCoord.

- Added missed strings to the XML
- Just adding unlocalized name to the effects list if localized string was not found in XML. I think it's a better than throwing an error.

- Refreshing gesture list after an item was copied

EXP-1908 FIXED (Gesture floater is not refreshed when deleting more then one gesture from Inventory)

- Updating moved items, to update model's modify mask.

- Added updating for Estate name and Estate owner name

Save *window* width and height, not client area

EXP-1891 FIXED ('Vehicles' category overlays avatar thumnail after setting minimal width in Avatar picker floater)

- Increased min width of the floater

- Adjusted width of the panel which contains the shop button

EXP-1546 FIXED (received items - purchasing some bodyparts and clothing from a prim marked for sale show wrong inventory icons)

- In buy floater, for multiple WEARABLES inventory items show corresponding wearable icons

Symptoms: Viewer window shrank by a few pixels on each startup.
Reason:   We used client rect (which did not include the window border) to create the viewer window.
Solution: Convert client rect into window rect, i.e. expand it by the border size.

Fixing the cases missed in EXP-1879.

EXP-1819 FIXED (Location & Favorites bar splitter should be draggable to 200 px on left and 150 px on right. )

- Allowed dragging to the left to shrink location to no less than 410 pixels, and to the right to shrink favorites to 185 pixels

EXP-1546 FIXED (received items - purchasing some bodyparts and clothing from a prim marked for sale show wrong inventory icons)

- Return focus to the previously focused root view

only show hourglass and fetching text when downloading folders, not item metadata

fixed layout stack so programmatic size updates will work correctly
