Choosing good keywords for tickets

Trac can search the full text of tickets, so adding a keyword that already occurs in another field doesn't help for general searching. If we standardise the use of certain keywords, however, it could make finding certain specific types of ticket much easier. This, then, is a suggested list of keywords that we might like to standardise.
