* remove unused WindowsNotes.txt
* various sm-ssc -> StepMania (and similar) changes
* Rewrote a bit of recommended_practices.txt
* Fix a copy/paste typo in anatomy_of_an_actor.lua
* many other things I can't remember; namely newlines at the end of files
This should make it possible to build StepMania 5 on Mac OS X.
The catch is that it will only work with Snow Leopard and up, but I think this is better than nothing.
We can support PowerPC / 10.4-10.5 again when someone can make the old Xcode 3 project work.
