[keycloak-dev] fine grain permissions merged

See https://issues.jboss.org/browse/KEYCLOAK-3444 It its currently limited to single realm administration. Can't define master realm fine grain permissions. It was too much of a pain. Also fixed the long standing issue of when admin with manage-users role could upgrade their management permissions. I'll be working on documentation in the next week or so and will get something in by 3.2 Final. Regards, Bill
