Add jQuery 2.2 and 3.0

The attached patcj adds jQuery 2.2.4 and the option to select between jQuery migrate 1.2.1 and 1.4.1.
Patch is rather large because it adds new versions of jQuery, personally would have prefered it to submit a pull request for patches this size :)

The update to 3.x is not in this patch because we (at the office) did not test if sites are actually working with jQuery 3.x.

New patch contain jquery 2.2.4 and 3.1.1

I also need a serious jquery update, and have been trying this, and am a little confused here -- Do I need to install both patches #4 and #6 to get a jQuery 3.1 installation? I've installed (just) #6, and am having some problems with .once() not being found (e.g., `TypeError: $context.find('input.autocomplete').once is not a function. (In '$context.find('input.autocomplete').once', '$context.find('input.autocomplete').once' is undefined)`. Thoughts?

Update: That call to `$context.find` is coming from the bootstrap version of misc/autocomplete.js, btw.

@jim_at_miramontes thanks for feedback

Drupal core do not fully compatible with jQuery 3.1

There is issue Incompability with jQuery 3.1

There are might be more issues...

unfortunately i could not reproduce your issues with 'jquery.once'

Thanks for the pointer! The problem I described above was my own fault :( -- one too many external library files getting loaded -- bur I'll check out your link/patch. In the meantime, will I be OK If I just have installed patch #6 (and dealt with the other issues you mentioned), or do I need to install patch 4 as well?

@jim_at_miramontes Patch #6 should be enougth

There is patchjQuery Migrate update for adding jquery_migrate 3.0.0 which should help to resolve some incompatibility issues with jQuery 3.1
