Incremental commit; added new loader function designed to grab edit-cache data instead of static-db data.

Created a second admin loader for callbacks that need to generate an edit cache (for ajax callbacks)

Incremental commit; refactored most of the admin callbacks to be (partially) compliant with FAPI, and to deal with the new logic-at-the-loader-level approach.

Incremental commit. Added separate static cache for loaded panels_pages and took steps to ensure consistency in its data. Some additional docblocks, and other small touchups.

I'm probably going to write a single FAPI pass-thru for all or most of the individual admin form page callbacks. Eventually.

1. Expunged all render-time uses of quickref, since we're abandoning that method.
2. Added calls to load the display along with the panel page for admin screens.
3. Added a bit of docblock.

Incremental commit; docblock tweaks, and minor refactor of one validator (which has been backported, minus string changes).

Rolled back earlier changes to admin path schema - $panel_page->name now precedes the action verb (e.g. edit, export) again.

Reinstated the %map arg on several admin callbacks; changed the storage mechanism for the loader flags;

Scratched a couple more unneeded bits from the mask. Moved mask storage directly into the panels_page table, and updated load functions accordingly.

Killed some more of the unnecssary bitmask items; fixed typos; improved hook_menu() readability; safely reconstituted the panels_page_get_current() function for API consistency from D5.

Considerable refactoring. The separation between logic/loading functions and rendering functions is almost complete, now.

Fixes for E_NOTICE compliance with $load_data. Moved access check to later in the master loader; we don't want Panels denying access to things that it's not overriding!

Removed suuuuuper crufty ajax functions - they hadn't been in use for who knows how many months, and nobody noticed :)

Moved the admin wildcard loader out into the main panels_page.module file (where it should have been in the first place), and rejiggered the paths to match up with the new editing paths (action verb before $panel_page->name). The new paths may be rolled back.

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.

Fairly large reorganization, although not much change in the logic. Most notable big item is that hook_menu() and hook_menu_alter() are now separate again, and the functions have been reorganized to place the two that hook_menu() calls at the top of the file (purely for conceptual clarity).

Also switched over to the use of a 'flags' field in the router quickref table, which is where we tuck as much of our behavior-governing bitmask as possible during the actual menu build process.

Incremental commit - numerous behavioral changes. Admin loader relocated to here; re-added implementation of hook_menu() as it now appears possible to cleanly separate it from what must be done in hook_menu_alter(). Cleaned up some docblocks, moved other functions around...lots of stuff.

Shifted all possible render preparation functions into panels_page.render.inc; also added an @file description to it.
