style($browser): remove ws, fix typo
fix($location): $location.path() behaviour when $locationChangeStart is triggered by the browser

Fixed inconsistency in $location.path() behaviour on the $locationChangeStart event when using
back/forward buttons in the browser or manually changing the url in the address bar.
$location.path() now returns the target url in these cases.
