[CLOSED PR] Remove RCD from ghostdrones

[Chickenish]

Granted it means antags can also permanently get rid of ghost drones with enough effort, but I don't think that's necessarily a bad thing.

that would certainly resolve people's concerns i think about the drone law 1 interpretation issue where people want to be able to bomb things or destroy sections and have it be left like that; make them do just a little high risk defense work afterwards to get rid of any drones and then have the high reward of a destroyed, airless section that's potentially not transversable.

i'm also partial to whitelist ideas for building roles if it means keeping some of the tools; i understand not piling more on admins in a separate selection process so i think the easiest implementation for that would be to do what brixx said and make it a mentor-specific role too.

i really, really, really want to like the cardboard RCD idea, and liked it when it first came about, but i think it might not address low-effort griefing of build-mode stuff like mazes in escape or layers of walls; even though they'remore fragile, if someone is determined to be Bad with the role, i think they'd just make a 7 or 8 or 9 layer thick wall or w/e in lieu of a 2 or 3 layer thick wall. maybe in addition with other controls like higher battery use or something. i'd be interested to see how it plays, though, i've been intrigued by the concept for it for a while. 

if admins are also tired of reading between the lines on Every Drone Grief Ahelp Ever about what is/isn't breaking laws for interactions, and there's a rework of that maybe in mind to move drones to a separate z-level or prefab, i think that could also be a safe and controlled way to play with construction in an environment like the afterlife bar or vr. also i feel like the name "Drone Zone" is a good opportunity, but take that for whatever it's worth.

As it is currently implemented, taking apart cardboard with a cutting or snipping tool takes three seconds to remove the plating, then three seconds to cut apart the girder. The action bar for this is not interrupted by starting to cut apart another wall/girder, meaning you can cut apart all the walls/girders within reach at once.
Constructing a cardboard wall with the C-RCD takes five seconds and 300 power units, and is not interrupted by doing more RCD operations. As you can place a wall on yourself with the RCD, this means you can place two layers of wall at once, each three tiles wide.

If it was a window, it would only cost 200 power units instead of 300 and only take 2 seconds instead of 5, but would have no girder stage to slow down the spaceman; if the window disassembly action bar wasn't so slow en masse it would also be a viable method.
If the spaceman in question did not have a cutting tool, any melee or thrown weapon could be used to crumple the walls, with the chance to crumple being force/throwforce*3, this would also have a chance to skip the girder stage.

In practical use, this means the 9 layer thick wall would take roughly a minute for a single player to cut a 3*9 chunk out of it, and it would take roughly 50 seconds and 8,100/15,000 power units to construct; even filling a two wide hallway for nine tiles would still cost 5,400/15,000.
A cardboard maze would be even faster to disassemble, as the scissors would be able to access more tiles at once and have less tiles to remove, and the ghostdrone would not be able to build this much faster, as doing so would require slowing itself down with the maze it is building.

If required, I could fiddle with the numbers a bit.

TL;DR: ghost drone build fast, spaceman destroy faster if have cutting/snipping tool, if no have snipping tool but have hitting thing, can destroy fast enough to get cutting/snipping tool.
