User Management API

[ianlgnk]

I've faced a problem that is OpenBoxes API doesn't have support to control properly the roles of a user. For some reason, when you try to pass many roles on a POST or PUT in the "generic/api/user" with:

{
    "roles[0].id": "3",
    "roles[1].id": "5"
}

Look what happened in the database:

mysql> select * from user_role where user_id = 2;
+---------+---------+
| user_id | role_id |
+---------+---------+
| 2       | 3       |
| 2       | 3       |
+---------+---------+
2 rows in set (0.01 sec)

It duplicates the first role for the user, trying to pass 3 roles, it will triplicate, and follow this bug for all roles you pass.

Another question is, it could be possible to catch all the roles associated to an user by his id, this would help so much to control OpenBoxes user access by your own system using API. Until now, I haven't found a way to do it...
