fix(core): parse URLs using the browser's DOM API
docs(ngRepeat): add example for filters in conjunction with `track by`
docs($window): improve style and clarify wording
docs(input): fix example

The input [number] error spans did not show on the example, as they were
relying on an non-existing property (myForm.list.$error) vs the working
property (myForm.input.$error)
fix(Scope): ensure that isolate scopes use the main evalAsync queue

Previously any $evalAsync task scheduled from a isolate scope or a child of an isolate scope
would never execute because we never flushed this queue
fix($compile): always instantiate controllers in parent->child order

Previously it was possible to get into a situation where child controller
was being instantiated before parent which resulted in an error.

Closes #2738
chore(dump): remove dead code

This code is not being used any more and the test is now failing
due to Karma changes. Karma used to expose window.dump but that
changed recently and that's why our build is now failing.

I'm removing the code and test, but we still need to figure out
how to route window.dump through angular.mock.dump, but that will
have to be a separate commit.
