jQuery: Added missing overloads with tests + contributors to head

Hi Guys,

I added a number of missing overloads (with tests where necessary) and their associated JSDoc comments.

I also added all identifiable contributors to this file to the header.  Finally I amended the version to reflect that it supports both the 1.10.x / 2.0.x jQuery code branches (these both share the same API but under the cover the 2.0.x branch doesn't support IE 6 - 8)
