Adjusted some naming to have slightly shorter variable names (pw_gen). Removed need for section in password generator. Adjusted passing of the renamed variable around and the other places pw_gen should be used. Added helper class that can be used by both pw_gen and cfg to get ids and adjusted print out of the config to now just print out the shared cache, which seems to make sense to me.
