fix vidbull; add crypto support as resolver lib

In case this approach is accepted, I tried to make this as easy as possible to review. This only contains files directly required for aes ecb, nothing else. Additionally, the only changes made were to add the "lib." prefix for library import.

I like cryptopy, but it comes with an odd gpl incompatible license. Another option might be pyCrypto, but it will take some doing to find out if it is included on all standard xbmc environments. There are other options that have better licenses, still looking around for a good alternative crypto suite.
