Catching HEAD back up with all the changes on DRUPAL-6--3. Now ready to move forward with the 7.x port!

Changed post-arg context build check to be aware of the fact that we now use error codes for argument plugins, and it should only load add'l contextual data if the return is an object (aka, isn't numeric)

View panes display plugin. Note that this checkin may break a bunch of content types because I added $subtype to some content type declarations and need to go through all the content types and update the render and title functions.

Tweaked pane rendering to skip creating a title if no title was returned by the pane render callback.

Just need to get the delete button working and then go through all the contexts, relationships and arguments to make sure their forms are working.

plugin loading.

Original fix was made in version 1.1.2.47 of plugins.inc.

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.

Initial D6 work -- this includes only panels.module stuff. Right now the drag & drop display editor works, layout, layout settings and render works. Special features such as cache and styles may or may not work.
