Should be able to customize resolutions

[gsymons@…]

The ability to customize the resolutions would allow Trac to be better adapted to an organization's process. For example, I'd like to have my customer enter user stories as tickets, and if they try to cram too much into a single story, I'd like to be able to have my devs close the ticket with a resolution of "SPLIT" so we can easily pull up a list of such stories. Other possibilities could include closing a ticket with a resolution of "REVIEW", and automatically (through a periodic script) reopening those tickets after a certain period if they haven't been reviewed. #905 illustrates another use of custom resolutions.

Since the resolutions themselves appear to be stored in the enum table, it would seem to be fairly simple to add this functionality to trac-admin. I could probably see if I can come up with something, but I haven't really looked at the code yet.

Hmmm... didn't see #869 before I submitted this. Since NewWorkflow is more flexible than just custom resolutions, don't even bother on this one.
