Updated TP hook to work with latest REST API changes
Expanded regular expression to include some additional variations that I think are useful.

My team constantly wants to write "bug 123" or "ticket 123" in the commit message. Unfortunately the old expression would only match "bugid 123". I made the ID portion optional. "Case[s]" already works great but I added "Ticket[s]" as well. Would love for this change to be applied to the service hook.
