#596450 by Scott Reynolds: Provide an ajax command response to reset the modal to the loading state.

#424548: Add a warning about overridng pager settings with Views AJAX.

#552664: Make mc.js not die a horrible death when users have multiple copies of jquery on their site.

#558918: Collapsible can be set to remember state between page loads. Allow collapsible handle and content to be separated and not have to be divs.

#565808 by sirkitree: Replace /nojs/g instead of just "/nojs/" with ajax, allowing nojs to be the last item in a URL.

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!

Expand the context to allow the plumbing for replacing placeholder contexts with real contexts for preview.

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