#307628: Fixed creation of $panel_args in the panel_page menu handling system to contain raw id values, as expected by views and node content for string substitution.

Stupid (evidently) unncessary call to panels_context_load_contexts() seems to have been the whole problem. Contexts are now being loaded properly...YAAAAAAAR!!!!!!!

This means we may well be ready for the first alpha release...

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

Save routines should now pretty much be functional. The problems appear to now pretty much be limited to context loading/generation at render time. It's not clear if the problem is with panels_page logic, the Panels engine, or some squirrely D6 changes.

Docblock updates and changes in code style for references to match merlin's ($a = &$b instead of $a =& $b)

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

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

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.
