added automount home directory support. contributed by simeon@bangor.co.uk

and a mini bug-fix by rob.nacarrato@sheridanc.on.ca

reads in an entry from the auto.home file for the user when they log in,
and mounts their home directory as the default path for the [homes] service.

i might add this as to the %substitution system, so that you can
specify subdirectories for the user profiles, mainly.
