Trac needs a central config file

[Manuzhai]

I was just trying to trick the mod_python handler into displaying a prettier page where you can choose from different projects, and while I got it done in the end, it was not a very pretty solution. This was mainly due to the fact that only the env knows about things like template locations, htdocs_location, and other stuff.

To make it easier to use Trac with multiple projects, I think Trac should have a central configuration file (e.g., /etc/trac.ini) which contains defaults for all the options in the env trac.ini that are reasonable. These options can than be overwritten in env-specific trac.ini's.

Would this be as useful as I think? I could whip up a patch if necessary. :)

Patch that adds a CENTRAL_CONFIG var.
