[development] Aggregator API

[Ken Rickard]

I had a discussion at OSCMS (with merlinofchaos, I think) about the
tangle of contrib modules trying to replace Aggregator.

As promised, I have posted an API framework requirements doc as a
result of that discussion.

The API would allow all aggregation modules to share a single code
base, rather than duplicating code and (potentially) opening security
holes by processing feeds in untested ways.
