Adds state API

Replaces the several state flags, mainly part of the drag feature, with
a state API. The state API be consists of the following methods:

 * `enter` - enters a state by name
 * `leave` - leaves a state by name
 * `is` - checks for a state by name
 * `register` - register tags for a state

The possiblity to use tags for states improves the decoupling of
plugins. The default tags are `busy` on system level and `interacting`
on user level.
Improves autoplay plugin

Simplifies the autoplay plugin by using the state API.

Changes support plugins API

It seems to be pretty common to extend jQuery's `support` utility (e.g.
Twitter Bootstrap and jQuery Transit). Regarding to the documentation
(http://api.jquery.com/jQuery.cssHooks/) `$.support.<css>` should be set
to a string of the vendor-prefixed version of `<css>`. For `transtition`
Twitter Bootstrap doesn't respect this convention but this was easily
fixed with a string object.

The default support plugin has been leaved as simple like before to keep
the maintenance easy. For a better feature detection the Modernizr
support plugin should be used.
