rpcclient.py must call XML-RPC functions with all arguments.
Removed encode_args and decode_args. They were the source of most of the
argument pain. Now opts is alwyas appended to the end of the arguments
so MUST be the last argument in any server-side function (can be None)
Allow the User object to handle unicode data
Small fixes to command-line tools to be friendlier
Broke out get_user() into get_user_by_dn() and get_user_by_uid()
Need to request more than just 'nsAccountLock' attribute when trying to
see if a user is already marked deleted. If it is blank the record
coming back is empty. Add 'uid' to the list to guarantee something coming
back (dn is handled specially)
Added user_container attribute to get_user_* and add_user so the caller
can specify where in the tree the user will be searched for/added.
Added global default value for user_container
