Add option to the installer for uid/gid starting numbers.
This also adds a new option to the template system. If you include
eval(string) in a file that goes through the templater then the
string in the eval will be evaluated by the Python interpreter. This is
used so one can do $UIDSTART+1. If any errors occur during the evaluation
the original string is is returned, eval() and all so it is up to the
developer to make sure the evaluation passes.
The default value for uid and gid is now a random value between
1,000,000 and (2^31 - 1,000,000)
