fix($compile): update '@'-bindings in controller when bindToController is true

'@'-bindings were previously updating the scope when they ought to have been
updating the controller (requested via `bindToController: true` + controllerAs).

It's a one-line fix + test case.

perf($parse): execute watched expressions only when the inputs change

With this change, expressions like "firstName + ' ' + lastName | uppercase"
will be analyzed and only the inputs for the expression will be watched
(in this case "firstName" and "lastName"). Only when at least one of the inputs
change, the expression will be evaluated.

This change speeds up simple expressions like `firstName | noop` by ~15%
and more complex expressions like `startDate | date` by ~2500%.

BREAKING CHANGE: all filters are assumed to be stateless functions

Previously it was a good practice to make all filters stateless, but now
it's a requirement in order for the model change-observation to pick up
all changes.

If an existing filter is statefull, it can be flagged as such but keep in
mind that this will result in a significant performance-penalty (or rather
lost opportunity to benefit from a major perf improvement) that will
affect the $digest duration.

To flag a filter as stateful do the following:

myApp.filter('myFilter', function() {
  function myFilter(input) { ... };
  myFilter.$stateful = true;
  return myFilter;
});
