No support for local Hipchat servers because of a hard-coded URL

[Jason Tiscione]

In lib/hipchat.js on the very first line, the server URL is stored in an inaccessible closure value that is set to a hard-coded string:

var API_URL = 'https://api.hipchat.com/';

Instead of pulling a hostname from globalAuth.json that defaults to api.hipchat.com, this code simply forces you to use api.hipchat.com, which breaks support for Hipchat team servers for no good reason.
