0.2.1 Alpha Released

This is a very tiny bug fix for some (infrequently) malfunctioning menus.  I've seen the menu fail to work just after entering fullscreen mode and yesterday I got a bug report that the menus do not work at all when running on a Mac.  I hope this fixes that, as well.

Aside from that, there's a small bug fix for something that wasn't being logged.  The Alpha color variable was being installed as a Built-In Variable, but was not being reported as such.
