Name all anonymous watch functions in Angular

[IgorMinar]

Instead of:

$scope.$watch(function() { ... }, function() { ... });

we should use named functions everywhere, like this:

$scope.$watch(function fooWatch() {}, function fooWatchAction() {});

With the name in place, debugging using js debugger is easier and batarang can provide more useful output (e.g. in the perf tab).

I have just sent a PR from my name-anonymous branch which does this.

+1. Cannot wait to use this in the debugger.
