docs(header): replace logo.png with logo.svg

The current logo looks awful on high-density displays.  SVG is a
better choice because it can scale to any resolution without
increasing file size.

Amending #2775 to add support for IE 8 by falling back to existing PNG
with img.onerror

Using relative URLs as directed by @btford and @petebacondarwin.

Closes #2874
fix(resource): check whether response matches action.isArray

When using $resource you must setup your actions carefully based on what the server returns.
If the server responds to a request with an array then you must configure the action with
`isArray:true` and vice versa.  The built-in `get` action defaults to `isArray:false` and the
`query` action defaults to `isArray:true`, which is must be changed if the server does not do this.
Before the error message was an exception inside angular.copy, which didn't explain what the
real problem was. Rather than changing the way that angular.copy works, this change ensures that
a better error message is provided to the programmer if they do not set up their resource actions
correctly.

Closes #2255, #1044
fix($q): call `reject()` even if `$exceptionHandler` rethrows

Normally $exceptionHandler doesn't throw an exception.  It is normally
used just for logging and so on.  But if an application developer
implemented a version that did throw an exception then $q would never
have called reject() when converting an exception thrown inside a `then`
handler into a rejected promise.
fix(mock.$log): keep in sync with $log

fix(jqLite): support space-seperated events in off

feat(scenario): expose jQuery for usage outside of angular scenario

The global jQuery reference is removed by angular scenario and only a local scoped reference is kept. To make jQuery available for other code, a new reference angular.scenario.jQuery is added.
fix(mobile-ng-click): prevent unwanted opening of the soft keyboard

Ghost clicks are busted but the corresponding form elements are still focused. This means that for example on smartphones the soft keyboard will be opened. This pull request prevents the unwanted opening of the soft keyboard.
fix($parse): unwrap promise when setting a field

This fixes an inconsistency where you can't call the setter function
when the expression resolves to a top level field name on a promise.

Setting a field on an unresolved promise will throw an exception.  (This
shouldn't really happen in your template/js code and points to a
programming error.)
