ptyaim 0.2; notes on Mac OS X

Here is ptyaim 0.2. ptyaim now supports AIM chat rooms, and IRC. There are also a lot of bugfixes and ptyaim is closer to doing the "Right Thing" at all times.

I've also looked into porting to Mac OS X. Don't expect this. Mac OS X has no dlsym(), but that is easily wrapped. The real problem, though, is that Mac OS X does not have poll(). So don't expect ptyaim to run on it soon.
