ng:class as well as ng:class-odd and ng:class-even always reset the class list to whatever it was before compilation, this makes it impossible to create another directive which adds its own classes on the element on which ng:class was applied. the fix simply removes all classes that were added previously by ng:class and add classes that the ng:class expression evaluates to. we can now guarantee that we won't clobber stuff added before or after compilation as long as all class names are unique. in order to implement this I had to beef up jqLite#addClass and jqLite#removeClass to be able to add/remove multiple classes without creating duplicates.
