Issues outstanding:
If we're going to have version numbering on the main objects, maybe the control board should find the rezzor by a heartbeat listener (or vice versa), so we don't need to change the config card each time?
Should the control board (at least) have the name "RezMela" visible on it somewhere?
Should updater only accept objects by the same owner (to prevent script injection)?
Deployment checklist:
All scripts must be set to copy-only. including in child prims. Firestorm's permissions setter seems to be working OK for this, but we need to check manually to be sure
All objects must be set to no-transfer.
Categories notecard should have placeholder categories
Board and rezzor should be renamed ("RezMela rezzor", "RezMela control board"), including rezzor name in control board's config card.
Object Picker v0.12 and Updater v0.5 are minimum
