- Removed logging for MAINT-3555
- Added NULL guard to fix MAINT-3703 (hopefully)

 - LLFloaterView::mToolbarRects[3] was transformed to LLRect mToolbarLeftRect, mToolbarBottomRect, mToolbarRightRect;

about the return type for calls to LLView::getParent(): never assume a down
cast is possible.

- Removed a lot of logging code to reduce application close time

 - memory leaks fixing;

- Added clear() after DeletePointer() call to hopfully fix this...

MAINT-3710 FIXED List of members is removed from General tab. Title column is added to the list in Members tab. Roles tab is renamed to Roles & Members and Roles sub-tab is default now.
