This adds a dialog to the room settings in which the user can choose
which of these three event types they want to hide (additionally to the
default):

  - m.room.member
  - m.room.power_levels
  - m.sticker

The current state is read when room settings are opened and saved when
new settings are accepted.

Allows you to zoom and pan now.
