Added windowDidResize: to the Mac OS X delegate for resizing windows. Now to figure out why I can't resize windows myself...
Fixed non-minimizeable windows in Mac OS X; it was a simple copy-paste fail.
Attempted to fix the lack of resizable window borders by setting the NSApplication activation policy. This fixed it, and also fixed a bunch of other things, such as the application being seen as part of Terminal, lack of dock icon, lack of application menu, etc.
Some error message and TODO changes related to the previous commit.
