The patch converts the dock into a YUI shifter module and at
the same time improves several aspects of its operation.
The features of this patch include:
* Dock Module conversion.
* A loader that ensures we don't include the dock JS or its
requirements unless actually required.
* We no longer include the dock JS for themes that don't
enable it.
* Blocks no longer add registration events to the page
instead a dockable attribute is added to the html and the
loader looks for that.
* The dock module is properly documented and running YUIDoc
gives good quality documentation.
* We no longer need the dock module registration or
subcomponent.
* All events that can be delegated are now delegated.
* Removed unused variables and code left over after fixes.
* Support for docking blocks renderered using the new blocks
render method. Better support for custom block regions.
Improvements include:
* Alternative location might be useful when server administrator wants to maintain
a local copy of component cache instead of using shared $CFG->cachedir.
* Component caching is now enabled in behat tests which should improve performance.
* Standardised ignoring of component caching.
* Fixed debug mode in ABORT_AFTER_CONFIG scripts.
* General documentation improvements.
Better performance, more reliable, completely self contained,
more validation and full backwards compatibility.
This will also allow us to implement ignoring of plugins.
