Specify /billing handler

[Ryan J Ollos]

See also #12853, which is required for Trac 1.1+ compatibility.

[Russ Tyndall]

I have been quite busy this year as my company recently lost a valuable employee. I will try to get to this soon :)

[lkraav]

v2 patch includes additional db api compatibility updates.

The changes aren't actually big, just mostly about with env.db_query as db: indentation.

Looking forward to having you back, Russ

[Ryan J Ollos]

If you use db=None for environment_needs_upgrade and upgrade_environment, the patch should work for Trac 1.0 and 1.2.
