Support for agilo tickets

[chense]

Agilo for Trac defines its own ticket system (while disabling built in ticket API), and when trying to start/stop work for an Agilo ticket, I get AttributeError: 'Ticket' object has no attribute 'is_writeable_field'

I think this is similar to ​http://trac.edgewall.org/ticket/9452.

So, what can be done to fix this cleanly, rather than using Agilo ticket objects?
