This was removed inadvertantly in change 1fc92fc19c98.

- HandleDragAndDrop() method was overridden in the LLPanelOutfitEdit class to handle drag and drop operations of the Clothing, Body Parts and Attachments.
- In panel_outfit_edit.xml parameter allow_multi_select was set to true to allow multiple selections.
- Added class LLCOFDragAndDropObserver to implement the drag and drop.
- Class LLInventoryMoveFromWorldObserver renamed to LLInventoryAddItemByAssetObserver.

Drag and drop reimplemented using functionality of the LLInventoryAddItemByAssetObserver.

EXT-7106 FIX Change from commit callback to validate callback, remove some cyclic tab panel switches.

Problem was caused by incorrect use on Commit callback (which didn't actually prevent from tab switching) which leads to cyclic tab switching.
Validate callback actually prevents tab switching.

Two problems:
1. AvatarList didn't hide popup menu when goes invisible.
2. (Real problem) MenuHolder View didn't process TAB key. Which leads to changing active ("focused") control. Which leads to the ability (for example) to switch tabs and hide popup menu parent view.

EXT-7241 FIXED Changed all "Edit Appearance" links to "Change Outfit" and pointed them to the My Outfits tab.

Renamed the following menu items to "Change Outfit" and made them open My Outfits tab:
- Avatar in-world context menu -> My Appearance.
- Avatar inspector menu -> My Appearance.
- Me -> My Appearance.

To enable the Appearance SP switch to My outfits I cleaned up the logic of switching between my outfits <-> edit outfit <-> edit wearable panels.

Also done the following cleanups and minor improvements:
- Removed unused LLSidepanelAppearance::mEditBtn and mLookInfoType members.
- Removed empty LLSidepanelAppearance::updateVerbs() method.
- Made the "params" argument of LLSideTray::showPanel() and togglePanel() optional.

Fixed issue where mCurrentSelectedList was being used before NULL check.

* Added 4 buttons with tooltips:
 ** Build - Shows/hides Build Tools
 ** Search - Shows/hides Search
 ** Map - Shows/hides World Map
 ** Mini-Map - Shows/hides Mini-Map
* Made their width and minimal width the same as "Move" and "View" buttons (increased default total width of the bottom tray to make Layout Stack initialize its panels with default values from xml)
* Added appropriate menu items in context menu to Show these buttons in the bottom tray (with functionality)
* Set on click actions for this buttons. ("Build" temporary made disabled because default toggle registration is not enough for this floater.)

Dev Notes:
* Improved LLBottomTray::initResizeStateContainers to fill mObjectDefaultWidthMap using mStateProcessedObjectMap & mButtonsProcessOrder container
* Improved LLBottomTray::canButtonBeShown to process variable number of buttons that can be hidden on resize

QA Notes:
Resize behavior with new buttons can already be tested.

Fixed a logic error in LLViewerMediaFocus::getBBoxAspectRatio() that caused it to sometimes return bogus results.

Added a number of lldebugs messages to LLViewerMediaFocus::getBBoxAspectRatio() and LLViewerMediaFocus::setCameraZoom() that may be useful when working on the autozoom code in the future.
