Jquery event support

[lsnape]

Small change, switching the addEventListener for a jquery on event listener if the library is detected.

[jarohen]

Merged into 0.2.0-b3 branch (current working branch)

Couple of bits of feedback:

• Best to squash your commits down before submitting a PR so that the maintainer can follow a single thought process, especially if a couple of them were dead ends.
• I probably wouldn't bump version numbers - for public libraries, chances are your features/bugfixes are part of a larger release, so best to let the maintainers figure this out. (I usually cut a release pretty quickly for most bugfixes, but others like to pool them together, or sometimes a feature forms part of a larger refactoring - there are plenty of reasons!)

Good idea and good implementation though - cheers :)
