Allow Custom HipChat Servers

[c5f]

HipChat has a beta program for self-hosted HipChat servers.

redmine_hipchat currently assumes HipChat.com hosting only.

The self hosted servers are now available, are there any plans to update this plugin to support them?

There is a PR from Jan 2015 to fix this (not mine).
