Changes:
groups now a variable with a preset, since there may be instances
where sudo/admin will NOT be desired.
home now entirely a variable, defaults to previous action, but
handles cases where created user may not belong in /home
managed home flag, defaulted to enabled.
No impact to current functionality. Allows for more granular changes
in the future. Typo fix for managehome.
