EXT-2561 : Add standard bottom panel (gear menu, add button, trash icon)
Added gear menu and standardized the code. (someday, will create a subclass to share the functionality across panels)
Make LLPanelOutfitsInventory more modular, e.g. it no longer knows about the Wear/Edit buttons.

1. Changed sidepanel names to have "sidepanel" (e.g. panel_appearance -> sidepanel_appearance)
2. Changed some "Looks" names to "Outfits"
3. Changed LLPanelLooks to LLPanelOutfitsInventory (to match other inventory panel naming)
4. Took out tab from sidepanel_appearance.
