Explodes device.dmi (#80025)

## About The Pull Request

I woke up today and thought 'what would be easy thing to do today so I
can say I've done something?'. Then I remembered I saw several gangtool
usages the time I split radio up, and I could remedy those. 7 hours
later, device.dmi is split in a folder of its own, and I've also given
unique sprites to door remotes and landing desginators.


## Why It's Good For The Game

The device.dmi was kind of a mess.
