Cocoa : implement opening .blend file by double-clicking on it in OSX Finder

When the user double-clicks on a document file in the Finder, OSX doesn't simply give the filename as a command-line argument when calling Blender, as it is done in other OSes.
Instead, it launches the app if needed, and then sends an "openFile" event.

The user can also open a document file by dropping its icon on the app dock icon. But as this is not real Drag'n'drop, I've renamed the Ghost event to a less confusing "GHOST_kEventOpenMainFile" name.
