Updated LLView:

-Removed a few extra unneeded virtuals
 -Pulled tabgroups out of llpanel and into LLView
 -removeChild doesn't support delete. Delete manually.
 -addChildAtEnd renamed to addChildInBack
 -getScreenRect renamed to calcScreenRect
 -added calcScreenBoundingRect and calcBoundingRect(which updateBoundingRect calls
 -General cleanup. Someone at LL figured out that dynamic_cast actually exists.
Fixed PieMenu not reliably centering on cursor.
Fixed context menu crash in line and text editors.
Classes with LLEditMenuHandler as a base do not need to set gEditMenuHandler to NULL, since LLEditMenuHandler's dtor does that already!
