Animations are broken for SVG sub-elements if jQuery is present

[jonrimmer]

If jQuery is present, then Angular animations on SVG sub-elements do not work, as jQuery does not support adding and removing classes from them. It would be helpful if $animate always used jqlite to perform class manipulation, rather than deferring to jQuery.

will look at fixing this today, it should be just a small refactoring...

so the reason this is taking so long is, i'm having problems writing a test which fails --- there are cases where jQuery apis are used to add classes in ngAnimate, but I am having trouble writing tests to verify that they work.

I'll give it another go as I've been mostly out of commission for the past week.
