Fix for issue #27 - Can't authenticate (Status 301)
Fix for issue #27 - Can't authenticate (Status 301)

The discogsauth.py wrapper has become quite stale. api.discogs.com has long
since redirected (301) to their https counterparts. This is a temporary fix
to utilize https endpoints and get the tool back into working state.
