[1.0.0] Document the new ClientOptions and ServerOptions classes.

[ChadSikorra]

This documents the new ClientOptions and ServerOptions classes that replace the old associative array options that were passed into the client / server. It also replaces usage in the readme. Now that the options objects are in place, I can remove some redundant methods no the LdapServer class as well.
