- don't update browser before and after eval instead
  - sync location properties before eval
  - sync location properties and update browser after eval
- added tests
- symplified the code
- removed $location.toString() because it was not idempotent and useless

This resolves the issue with issuing two $route.onHashChange calls
when the $location was updated with a hashPath that needs to be encoded

camelcase is used for other angular functions and forEach is also
used by EcmaScript standard.

- rename the internal as well as the external function name
- tweak the implementation of the function so that it doesn't
  clober it self when we extend the angular object with an
  object that has a forEach property equal to this forEach function

Closes #85

 - There was a perceived lag when typing do to the fact that we were
   listening on the keyup event instead of keydown. The issue with
   keydown is that we can not read the value of the input field. To
   solve this we schedule a defer call and perform the model update
   then.

 - To prevent calling $eval on root scope too many times as well as to
   prevent drowning the browser with too many updates we now call the
   $eval only after 25ms and any additional requests get ignored. The
   new update service is called $updateView

- Browser now starts the poller on first call to addPollFn()

- Many services ($location, $cookies, $router) are no longer eager-publish. The result is that
  unless someone needs the $cookies, they will not cause the Browser to start polling for them.
