More extension points for reports

[anonymous]

We've written a small trac plugin, which extends from the main report module. It's main action is to tweak the sql used to generate the report, and then add some more fields into the report output. (The result is that the query can then run transparently across multiple postgres schemas, to give us an overview of several tracs)

With 0.10, we had to copy and paste a bit of the report module to get it all working, but not to much. With 0.11, we've had to copy loads more, as there are fewer extension points that are suitable.

The extension points that'd be really handy are:

• return of something like get_info(), so we can easily alter the sql that'll be executed
• something around the "Structure the rows and cells" step, so that we can add extra stuff onto rows. Perhaps split out the column based stuff, so you call a method per column?
• make the template names not hard coded, so we can override them without needing to touch anything else (we want the normal report templates unchanged for other stuff!)

Patch welcome, otherwise not for 0.12.
