[TYPO3-core] RFC: #10975: Update extJs to 2.2.1

[Steffen Kamper]

Hi,

this is a SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=10975

Branches: trunk

Why RFC?
because
1) add yui and jquery adapters (that was majority decision in thread #10964)
2) add ext-core (and ext-core-debug)

A patch file is too big, i think there is no need to attach one.

Please vote for 2) (and/or against 1) if you object)

vg Steffen
