- LLAppDelegate header relocated to LLWindow.  Definition is still present in secondlife-bin (for compatibility reasons when loading a nib).
- Return key handling fixed.
- Command key now acts the same as the control key by issuing control character codes when the command key is pressed.
- We now retrieve the window pointer directly from the app delegate in LLWindow.

OS X crash on startup fix: always ensure that mMainLoopInitialized is initialized properly within LLAppViewer::init().  Otherwise, the viewer will sporadically crash on start up.

- Removed the callback system in favor of simply defining functions in a header to later be implemented in whichever file is most convenient for what we want to do (i.e., calling LLWindow callbacks within LLWindowMacOSX, setting cursors in llwindowmacosx-objc.mm, etc.)
- Viewer shutdown now works appropriately
- Added a bit of debugging code to test if a key has been handled by the UI or not (useful for tracking down the mystery of the enter key not being handled)
- Setup a cocoa quit handler within the application delegate that intercepts any termination requests

- Updated to .xib format.  To produce a new nib (which is required after changing the xib file), use "ibtool SecondLife.xib --compile SecondLife.nib" within the newview directory.
- xib file now defines the viewer's window.  VIews are still being pragmatically added to the main window.  This may change in the future.
- LLAppViewer's main loop has been slightly refactored to be executed on a timer for OS X.  This probably needs a bit more work.
- Event handling still needs more work to work within a timer based event loop.  It works fairly sporadically at the moment, as if events are being dropped between timer executions, at least for the mouse.
- Carbon has been purged from the viewer's startup, and from LLWindow entirely.  There's likely still a few odds and ends fragmented throughout the viewer and its dependencies.  Need to track these down.
- LLAppViewerMacOSX now uses NSApplicationMain, and also implements the NSApplicationDelegate protocol in LLAppDelegate.
- Fullscreen support has been implemented for OS X 10.7+
This is still a work in progress, however at this stage everything needed for a functional viewer is (mostly) complete.  From here, it's mostly just bug hunting and fixing.

LLWindow: Move to using Cocoa for window and view creation along with setting up callbacks for event handling as such.

Removed duplicated block of code in LLAddBuildTest.cmake. Added comment to point to duplicated code. Replaced hard-coded tcmalloc link option with variable that is created in GooglePerfTools.cmake.
