Xcode: Mac OS X build fixed

I was originally going to split this up into multiple patches, but the Xcode project file format is a bit difficult to cleanly split for patching. So anyway, I've made a few changes:

  • Fixed Xcode 3.2 compatibility (complaints about using GCC 4.2 with the Mac OS X 10.4 SDK, among other things).
  • Removed the tilegen target (this is now done via a script)
  • Fixed the Crawl-tiles-cmd target
    • Now links to AppKit.framework and OpenGL.framework
    • Set the search path for the SDL, SDL_image and libpng frameworks to be /Library/Frameworks, which is standard.
  • Fixed the Crawl target
    • Now copies the necessary non-standard frameworks to the Frameworks directory (this eliminates the dependency on Fink).
    • Eliminated a couple redundant or worthless steps which did things we really didn't need.
  • Added precompiled header support to the Crawl-cmd and Crawl-tiles-cmd targets.
