Allow disabling accounts
We don't have a way yet to disable accounts.
Before #56 (closed), you could set "No access" to the dashboard. I haven't checked exactly what the consequences of that were and if that comes close to the wanted behaviour for disabling an account. Depending on that a quick fix could be to revert that change.
However I would prefer to have a separate button and state view for disabling accounts, rather than have it as a "hidden feature".
