Fixed View::dispatch and improved File::size

- View::dispatch: it was possible to fire the dispatch views more than once if an exception occurred.
- Inphinit\Experimental\File::size: Curl uses headers in FILE protocol, content-length can returns value with white-spaces or note (depends on the PHP version (or if you are using PHP or HHVM), there are no guarantees in the format so the space check is optional)
