0.4

Significant changes. Now compiled to work all the way back to Lion (though not tested on anything other than Mavericks). Has more configurations options and now lets you change them at runtime in the menu. Besides memory threshold and freeing pressure, you can now control the notification system (Growl or Notification Center) and the freeing method (memory_pressure or plain allocation).

Initial public release. Only supports Mavericks and up because it uses the memory_pressure command introduced then. Configuration is in a plain text file in the home directory and only checked on startup.
