Bump to Touch 2.2.1 and include all important js and theme files

Hi,

I bumped the Sencha Touch version to the latest, 2.2.1, and the pom now uses the same logic as the Extjs webjar, including all available js files (compressed as well as uncompressed, important for usage with Sencha Cmd) and the built-in themes (without the themes, the library is not usable).

Cheers,
