Create separate object for Users and Groups (using same base class)
Check for uniqueness before adding new users and groups
Remove user_container from everything but add operations
Abstract out a number of functions that are common across users and groups
Make sure all strings passed in to be in a filter are checked
Add new error message: No modifications specified

  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

object.  Based on rcrit's original patch.
Push scalar to list value conversion inside funcs.py.

Fix fields to be lowercase in web gui (server now returns them lowercase).
Fix ipaclient.py to refer to lowercase fields when adding a user.
Fix user.getValue() to check isinstance(value,list) instead of value[0].
