General Welding/Building parity

Vermidia commented 2 weeks ago

Description

In CM-13:

[ ] You can only build 1 thing at once (1 cade, 1 wall, etc)
[X] Welding/Building isn't cancelled by damage (partial, but for welding barricades it is now)
[X] You can only weld 1 thing at once
[X] Barricades heal a certain amount per weld (200 normally)
[ ] Barricades should block projectiles from more than 1 tile away on the front, and 4 tiles away from the back
- Some projectiles have a chance to be blocked (boiler glob) and GLs can lob nades over. There may be a few other exceptions (check demo spec rockets for instance)
[ ] Hand-welders can only weld vents and doors
[ ] Barricades should be unweldable at a certain point

A good amount of these can be fixed by barricades using RMCRepairable, if that was fixed to use fuel by now.

Mostly putting a list down now since it isn't in our issues list anywhere.

also: hand welders are too weak to repair barricades in CM13, you must use a blowtorch
