Smarter GET variables for the test runner

[flesler]

With this patch, the test runner can be customized some more.

It accepts things like this:

/jquery/test/?core&event
/jquery/test/?!ajax&!selector
/jquery/test/?core&!makeArray

The logic behind is like this:

If no restriction is found then
   execute all.
Else if(when) there's a match, then
  If it's a not(!)
     dont execute this test
  Else
     execute this test
Else if it's a not
  Signal this as ok, but keep checking

This logic allows multiple nots, it seemed to me like the expected behavior. I consider this very useful to run only a couple of tests, or specially a !ajax tests (it nearly hangs for me).

Additionally, I added a test that fails until the patch is accepted (by Jörn's request at #2619). We could have some kind of name agreement that this kind of tests, include an "experimental:" or something like that.

Then you can run test/?!experimental: to avoid seeing useless failures.

I hope this is useful.

I've refactored the filtering ([5307]), but was unable to apply your patch. Could you adjust it to the current revision?

Also, for some reason, when applying a patch from you, my svn client shows me that the whole file changed. Odds are good that my Eclipse or Eclipse SVN plugin screw it up. Anyway, could you check that you use UTF-8 and unix-line-delimiters when creating your patches?

Anyway, its really hard to exclude tests via regex, eg. blacklist instead of whitelist, so I like your approach.

Works fine. Needs some documentation though.
