113 hipchat api v2 compat

Fixes #113 (HipChat API v2 Support)

So manual testing works fine for both API versions. However, this patch
being integrated into the website, provides only suppor for API v1.
It returns 401 for API v2 keys.

Maybe it's something with my configuration. It would be nice if anyone
else could also test.
I dont think they care, they can paste either in and it works. Having it there complicates matters for users.

Also people wont know that its changed unless they remember what the string was before, and I dont want them to go in and update anyway :-)
