As far as I know there isn't any real way to tell when the clipboard contents have changed without polling them, so I didn't implement the clipboard update event on X11.

Fixed generation of SDL_revision.h when hg is in the path set up in .bash_profile

A complete clipboard implementation would support multiple formats that could be queried at runtime, events for when the clipboard contents changed, support for HTML, images, etc.  We're not going that crazy, at least for now. :)

Updated iPhone demos (which build and run again)

Fixed position calculation for centered windows
