jqLite previously used `elt.className` to add and remove classes from a DOM Node, but
because the className property is not writable on SVG elements, it doesn't work with
them. This patch replaces accesses to `className` with `get/setAttribute`.
`classList` was also considered as a solution, but because only IE10+ supports it, we
have to wait. :'(
The JqLiteAddClass/JQLiteRemoveClass methods are now also used directly by $animate
to work around the jQuery not being able to handle class modifications on SVG elements.
Closes#3858
- ngAnimate directive is gone and was replaced with class based animations/transitions
- support for triggering animations on css class additions and removals
- done callback was added to all animation apis
- $animation and $animator where merged into a single $animate service with api:
- $animate.enter(element, parent, after, done);
- $animate.leave(element, done);
- $animate.move(element, parent, after, done);
- $animate.addClass(element, className, done);
- $animate.removeClass(element, className, done);
BREAKING CHANGE: too many things changed, we'll write up a separate doc with migration instructions
