load dashboard based on rolename(s)

[gbin2265]

We link the icingaweb (icingadb) to a Microsoft AD and there will be more than 500 possible users. In order not to have to create a dashboard for every user, I propose these modifications.

If the user does not have his own dashboard, and the user is linked to a role(s) that has a dashboard folder based on the role name, he will load it.

If there is no user or role dashboard and a default folder with a dashboard exists, it will use it.
