Huge update to ITFoundation. I've gone through every file (except queue.h and queue.c) and fixed tabs and updated the header prefix comment to the current style we're using. I've also tried to do a good job of setting the subversion properties to match my auto-props. I've also updated build settings so that it only links against Foundation and updated or removed things that required AppKit or GUI portions of Carbon, or otherwise belong in a different framework (such as ITKit).
Organized the project some. Added some framework XML classes.
