[TYPO3-project-4-3] extJS files

[Martin Kutschker]

Currently the idea is to use the big ext-all.js in the Core. We could
also use all the single files but that's a pain to maintain and means a
lot of single file includes.

But OTOH the Core won't need the Air package. Very likely it won't need
the form classes as well.

So what do you think to split up the JS file into two or three files.
One base file and one or two extension files depending on the base file.
