Praetorians can put sticky beneath resin doors

[Casgair]

Assuming this isn't behavior as intended:

Bug Description:
By opening the doors prior to a spit, Praetorians can use their resin spit to get resin beneath doors, something that's no longer allowed through the usual resin build code.

Steps to reproduce:
1. Open resin doors
2. Spit in their vicinity
3. Observe how you now have a door tile with resin underneath

I don't think it's a bug, I'm pretty sure it's just a balance implementation but what do I know. I don't play xeno all that much.
