Cocoa: Remove subclassing of NSApplication

Browse Source 
This removes the GLFW NSApplication subclass as a step towards better
coexistence with other libraries that touch Cocoa.

This moves application object creation to platform init to allow event
processing before window creation.

Related to #1317.
