Implement used modification functionality

This adds user information modification functionality to nslcd and pynslcd and
implements a chsh.ldap utility that can be used to change the login shell of a
user (similar to the normal chsh command).

The user modification functionality should allow for generic modifications of
user information. More utility commands to perform modifications remain to be
implemented.
