Key view loop fixes/improvements

• Removed unnecessary code at beginning of CPTextField -becomeFirstResponder that might have been a hack to get around a bug I fixed.
• Fixed race condition in setTimeout closure in CPTextField -becomeFirstResponder.
• CPWindow -setInitialFirstResponder now works reliably and follows Cocoa behavior in that if -makeFirstResponder is called with something other than the window before the window is first shown, it will override the initial first responder.
• Like Cocoa, until the first responder is set during window load, the first responder is the window by default, not the content view.
• Optimized search for any view that has a previous/next key view set.
• Sheets can become key windows again.
• CPWindow -recalculateKeyViewLoop now just marks the loop as dirty, per Cocoa docs.
• CPWindow -autorecalculatesKeyViewLoop now behaves per Cocoa, it only has an effect when views are added or removed.
• If the first responder does not have a valid previous/next key view, it does not resign to nil, per Cocoa behavior.
• Code optimization and cleanup.
• Test app (KeyViewLoopTest) that demonstrates various scenarios. https://github.com/cappuccino/cappuccino/commit/782f47a30bb281005d1...
