Support for Mac cursors.

  TODO:
    o Allow reading from non-processed game executable. Now you need to get
      .bin file out of it
    o Use color versions of cursors
    o Combine MacResExtractor with Win32ResExtractor. Now I just stupidly
      create 2 objects and do not use new cursor caching code.
