Changed licenses processing for ad_mu

Created by: balcirakpeter

-Reason: There is a new attribute in which users main licenses are stored. That means, we do not need to compute licenses in ad_mu send script anymore. -Change: Both gen and send scripts were simplified. Instead of creating multiple files for roles and licences, gen script is creating for this purpose just one file ad_mu_groups_licenses.ldif. As for the other ous ldif files, ldif file for licenses contains all licence groups with their members. In adition, the msDS-cloudExtensionAttribute2 is also filled in gen script and added to ad_mu.ldif Whole code which computed actual main licenses was erased from send part. Every member is aded/removed to/from AD licence group by his membership in particular licence group from ad_mu_groups_licenses.ldif. Code which computed the msDS-cloudExtensionAttribute2 was also erased, because it is filled in gen script. -Result: Gen script was tested on small group structures and it seems to print correct results. Send script can be compiled but it is not tested on real data yet.
