Hopefully this patch will put an end to a painful series of bugs & unexpected behaviors related to panels_page titling.

#260278 by Pancho, sdboyer: Refactored save routines to be more consistent across the various client modules.

#264263 by Pancho: The menu system was being too strict in checking paths, so it was leaving out paths for tabs that should appear. Thanks Pancho!

#261949 by Pancho: Modify the preview admin form to let the admin user know about required arguments.

#267102 by Pancho, sun: Changed behavior of panels_mini and panels_page admin areas to run certain SELECT queries in batches instead of one by one, lessening the db load.

#271325 by douggreen, mdenson: Changed the _panels_page_get_title() logic slightly to show titles that were incorrectly being hidden in certain circumstances.

$panel_page->display was not being properly switched to the new, relevant display object in certain cases.

#263782 by Pancho, reported by bangpound: Fix panels_page_delete(), so it doesn't throw a warning when deleting a panel_page w/o secondary displays.

#260221 by sun, Pancho. Primarily codestyle cleanup; also fixed some missing leading slashes that were causing the edit icons not to appear in the new helptext for the display editor.

#261622. Made the logic for title selection a little smarter. Kind of a band-aid on a hemorrhaging wound, but it works for now.

#245204 by dhrgovic and sun. Added a little 'defensive' error checking to panels_page_move_tabs() to avoid protestations when its foreach() is passed a non-array.

#256582 by Pancho. Added some resiliency and use-friendliness (we hope!) to panels_page_add_page() by making it redirect to layout selection if an invalid layout is provided, rather than 404ing out.

#261797 by Pancho. E_ALL fixes: ensuring that vars are declared as new stdClass() before being used as classless objects. Also some scattered bugfixes here and there.

More quick db syntax fixes, courtesy of webchick's ninja-quick cvs-UPpage. Fixed main display db insert query, and added quotes around %s placeholder for the new switcher panels_page fields.

#256614 by Pancho and sun. Changed 'Next' submit button to 'Save and Proceed' on some panels_mini and panels_page forms; failure to indicate that a save WAS happening when those buttons were clicked was causing confusion.

#256646 by Pancho. Added helpful informational messages for when new panel pages/mini panels get created.

#256677 by Pancho. Changes to panels core client modules form settings to make them more user-friendly...and use proper English :)

#256684 by Pancho. changed $formid to $form_id in several panels add-on modules to meet drupal coding standards.

fixed panels_page_delete so that it properly cleans up any additional displays it may be leaving behind on deletion. Previously, it was only deleting the actual $panel_page->did (the default), and not any additional ones that may have been spawned.
