[mythtv] [PATCH] Add option to mythfilldatabase to change user

[William Uther]

Hi,
   I run my backend as root.  I recently switched from running 
mythfilldatabase as a cron job to using the internal method... it 
stopped working.  The problem was that with filldb running as root, it 
didn't have the correct home dir set, and so it couldn't find the 
tv_grab_au prefs.

   Attached is a patch to add an option to mythfilldatabase that allows 
it to switch users on startup.  This has two effects:
   - the home dir will be set correctly when it tries to get the grabber 
prefs
   - the grabber script is no longer being run as root

Cheers,

Will         :-}
