Title: Custom group names and WMIC to automatically detect group name based on SID

Adduser payloads :

CUSTOM group name
WMIC method of resolving the Administrators group SID (in cases where the group has been renamed or the system language isn't English).
COMPLEXITY checks against the provided password (warns if the PASS value doesn't meet complexity rules)

Broken out from PULL 247 (now closed) to avoid confusion
