#349724 by sarvab: Fix that ensures '{panels_page}.access' is properly formed, such that it can be used properly in panels_page_access().

Contains both some code updates and a db update to ensure consistency.

Some refactoring, partially to accommodate changes suggested by douggreen. The basic context-loading problem has not yet been solved, however.

Nixed the wildcards and stored_router fields, and changed 'meta' over to the much less annoying/more appropriate 'flags.' stored_router was collapsed into flags; wildcards may be restored later, but for the moment I don't think there's much value added in duplicating that data, so I'm content to calculate it on the fly.

We're most of the way there! Our separate data storage mechanism appears to be mostly working. Now the frontend loading needs to be done, along with the hook_menu_link_alter() stuff.

Panels Page now installs successfully, although the schema is likely going to change. The essential infrastructure for the menu system is functioning correctly. The secondary router storage mechanism, page callbacks, temporary panel data storage mechanism (for render callbacks) and a few other things need to be designed - but we're on the home stretch.

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.

About three-quarters of the way through the menu system port. Most of the guts are in place, although the bitmasks need considerable work and I've yet to work out a finite solution for sticking the admin tabs in wherever they might need to be.

Fixed doubled commas in the schema function - evidently they were residuals from one of Pancho's earlier patches

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.
