Change URL and add verification

Change the URL to point to the boxeed.in server since Github seems so

This allows us to also add md5 verification of the downloaded archives
We also changed the script around abit so that a failure in script
(download or extraction) doesn't kill the boxee processes or reboot the
box.

should be set correctly since B+ is already running.

Swap script execution order - Fanart and jump to last unwatched
