Alsa 1.021-1 upgrade script

Hi during my playing with the ASRock to get it set up properly heavy duty research and scripting to make it faster and simpler for everyone.

Please read here for more details as I added it to xbmscript topic for adding to main script as soon as the man himself flxfxp has time to play with it to improve loging/error support and what not.

Alternatively run xbmscript and when it loads type alsa and the upgrade will be executed.
