DRY camelcase

[cironunes]

Instead of two camelCase methods (one for jqLite and other for ngAria) I'm suggesting to make the camelcase method public so that we can don't repeat ourselves.

CLAs look good, thanks!

Actually this is a bad bit of code in ngAria. The attr.$normalize method on the attr parameter to the link(scope, element, attr, ...) function provides the ability to convert between the canonical and original attribute names, so ngAria should not be using its own version of camelCase at all.

@cironunes - perhaps you could provide a fix for ngAria instead of this PR?

@petebacondarwin - I got it. But, don't you think that this camelCase method be public? Or at least moved from jqLite?

I'm going to work in the fix for ngAria them. Thanks for the feedback.

@petebacondarwin: Do we want to document $normalize or is it intentionally undocumented ?
Since it's named $normalize and not $$normalize I guess is should be documented (@cironunes: hint 😉).
