add export/dump feature to mousecloak
yosemite removes CGSISCursorRegistered so we have to weakly link it and replace it
rewrite helper tool to be an app and install it per-user
quit app after main window is closed
use -dirty rather than isDirty for the kvo key
make sure the images are set as template to have them change color automatically
use weak properties for these outlets
This transformer wants a string returned, not an error
don't leak observation info on dealloc
more yosemite updates. NSViewControllers are now hooked into the responder chain so rename the menu action methods
