Some major restructuring, catching up to CTools. This is very much in process, there is a huge list of things that need to happen here still, but this may be checkpoint usable to the strong-stomached.

Initial port of panels mini; still need to work on the "context" ajax stuff and convert it to the new system, but the other stuff appears to work at least a little. Also include some fixes to layouts as "id" turns out to be illegal due to Drupal setting its own id string.

Templatize all panel layouts; give each layout its own directory for cleanliness. Slight improvement to the API needed for the move to work.
