Add a venue function

Brandon Adent

For those of us that use Proclaim in multiple venues, we need to be able to tag presentations and automation cues to a specific space (or give them a global option). This way all the automation signals that are relevant in one venue don't clutter up the list in another. This would also allow for digital bulletins to show up correctly for the space someone is in (could use BLE beacons or wifi to determine what room)
