Fixes error thrown when saving password and actually using the Umbraco membership provider
Adds ability to add/remove a single role to/from a single member, which is much nicer than having to instantiate arrays
Merge branch '6.2.0' of https://github.com/umbraco/Umbraco-CMS into 7.1.0
We don't really need to scream greetings to people who try to use the member picker
