megazoomer, full screen windows for MacOSX

megazoomer 0.4.1 brings full-screen windows to MacOSX. Just press Command-Enter, and the front-most window grows to fill your entire monitor. Press the same keys, and it shrinks again. Only works for Cocoa apps. BTW: the older versions of megazoomer caused errors in AppleScript based apps, e.g. iSquint.
