EXP-1065 FIX -- Inventory has slowed to a crawl. Clicking between items has an average one second delay. Same with switching between tabs.

* Removed numerous places in the code that called findChild across the inventory panel unnecessarily.
* Conglomerated uses of inbox and outbox inventory panels to the sidepanel class so the pointers can be cached and functionality like selection handling can be done more efficiently.
* Optimized LLView::childHasKeyboardFocus() to work backwards up from the focus object rather than searching for children that may or may not turn out to have focus.
