[CLOSED PR] Construction Worker rebalance

[Varali]

However, Nef's post gave me this idea: what if we raised the capacity of the regular RCD to 100, copied the RCDD's airlock construction mode and axed RCDD completely? Slight capacity buff is not really a big deal and the differences between two RCD versions after the nerf are minor enough to consider this merge a good solution.

This is honestly the biggest change I want out of a ConWorker change, as it'd make them far less crucial for any building projects that need doors. Want to build something as an Engineer but the Construction Worker hasn't latejoined or latejoined and cryod or fucked off somewhere? You're outta luck really, you can try printing doors but it's real finicky.
