Feature request: Change of Status away / DnD / activ

[ppabst]

Hello,
we use riot.im for the internal communilation of our employees.
Here it is often necessary that an employee can change his status to work undisturbed (DnD) or maybe just in the lunch break is (away).
A manual setting of the status would be very helpful here.
