== Save Game As Runtime ==

  * Fixed OS X support (finds a good default path for the player and can make runtimes)
  * Enforce extensions on OS X (.app) and Windows (.exe)
  * Added Copy Python option to copy the bundled Python to the runtime directory
  * Added Overwrite 'lib' option to choose whether Copy Python will overwrite a pre-existing 'lib' directory in the runtime directory
  * Added Copy DLLs option (Win32 only) to copy DLL files from the Blender binary directory to the runtime directory
  * Cleaned up the code to handle compressed blend files.
