Resurrect the old crash reporter and redo it to use HockeyApp for crashlog viewing. Fixes #1540
The old crash reporter was a separate process and replaced the system crash dialog, this one just sends a crash log (not automatically) the next time Adium is launched. We aren't using the HockeyApp SDK for this since there's some custom stuff we do in our crash reporter, e.g. check for updates and maybe launch the Xtras manager.
