2.2.1 release

I'm currently using the 8-4.0.2 version of aSmack for the use of EVE in an Android application. This also made is necessary to update smack itself with the new org.igniterealtime.smack package (the previous one used was a 2-3 year old (?) jivesoftware package).

To make this all work some small modifications had to be made to other EVE code: some changed classnames/methods and some more thrown errors.

Please consider adding these changes to the EVE 2.2.1 version.
