I just realized that this avatar is different case than our scripts in
the sense that OS doesn't know about it being on the unattended disk
and we copy the avatar manually so filename and extention are
redundant here as we can give any name to the avatar file as we need
from the scripts.

Sorry to ask you to change this once again but nothing very difficult,
just drop these paremeters/properties (both from code and xml).

I'll soon be submitting a patch to add API for apps to specify avatar
disk and location to the script.
