forward with the 7.x port!

Committing in a collection of ongoing port work from #589636, so that we can stop trying to track it all in patches.

Will make merging in changes (with an outside dvcs) from the 6--1 branch easier, anyway.

First steps toward updating CTools to d7. This contains some stuff found by coder module, plus css.inc should be fully ported. No testing performed though, so theres probably bugs. Need to write some tests or something.

Add a couple of support functions for ctools_set_page_token that are meant to be used by themes.

#545540 by Roger López: Add 5 page elements as available panes for using Panels as your primary page layout: breadcrumb, page title, messages, tabs and help box.

Remove the delegator module, introduce the page manager module. Anything that previously relied on delegator module must now change its code to rely on page manager instead!

More robust AJAX stuff that will eliminate some ugly errors plus prevent double clicks on ajax links.

Update export to make it more useful for Panels which does not always export in a straightforward manner.

Retool the access plugins to allow multiple plugins plus and/or switch. Retool selection criteria to use this allowing for a much richer selection of task handlers on a given page.

Checkpoint checkin: Can now create arbitrary pages! Yay. Task handler manipulation on arbitrary pages works, though there are some clear disconnects in the UI that will be addressed next. Not all page admin functions exist yet (no clone, enable, disable, revert, delete). Not all arguments have criteria yet.

Checkpoint checkin. Partial implementation of page task with generic subtasks, plus revamp of arguments, new access plugins (stolen from Views), updates to the wizard to make it fully compatible with the modal and some minor improvements to make it more flexible.

- a tool for AJAX, which is the next generation tool based on what Views uses.
- a tool for modals -- completely ripping the modal out of Panels.
- moving plugins for 'arguments', 'relationships' and 'contexts' into CTools.
