docs(httpBackend): update documentation for expect methods

`expect` methods can receive an Object as the data parameter, which was
undocumented.
fix(docs-bootstrap): Removed injector from bootstrapped docs samples

This is necessary to make e2e tests pass for implementing #3411. At present, the docs are violating the rule being enforced by double-bootstrap prevention.

chore(ngMobile): rename module ngTouch and file to angular-touch.js

BREAKING CHANGE: since all the code in the ngMobile module is touch related,
we are renaming the module to ngTouch.

To migrate, please replace all references to "ngMobile" with "ngTouch" and
"angular-mobile.js" to "angular-touch.js".

Closes #3526
fix(re-bootstrap): Throw an error when bootstrapping a bootstrapped element.

Nothing would prevent a user from accidentally calling angular.bootstrap on an element that had already been bootstrapped. If this was done, odd behavior could manifest in an application, causing different scopes to update the same DOM, and causing debugger confusion.

This fix adds a check inside of angular.bootstrap to check if the passed-in element already has an injector, and if so, will throw an error.
chore($q): rename `promise.always` to `promise.finally`

BREAKING CHANGE: the `always` method has been renamed to `finally`.

The reason for this change is to align `$q` with the Q promises library,
despite the fact that this makes it a bit more difficult to
use with non-ES5 browsers, like IE8.

`finally` also goes well together with `catch` api that was added to
$q recently and is part of the DOM promises standard.

To migrate the code follow the example below:

Before:

$http.get('/foo').always(doSomething);

After:

$http.get('/foo').finally(doSomething);

or for IE8 compatible code:

$http.get('/foo')['finally'](doSomething);
style(minerr): prefer component name as namespace
