Some improvements for groovyldap ref. implementation

[System Architect]

I loaded the source tarball, so do not provide a patch here - sorry.

I had to modify LDAP.java to make it work with both AD and ApacheDS

    * add   env.put(Context.REFERRAL, "follow");
    * add   public static LDAP newInstance( String url, String bindUser,
      String bindPassword ) to bind a s a user


I also created a pom.xml to enable Maven - attached. Please note - if
you use eclipse:eclipse to generate eclipse project - remove M2_REPO/...
from the project's libraries; Eclipse maven plugin does not need that.

Thank,
Oleg
