updatecover command

Forces every loaded build piece to recheck whether it's under a roof, instead of waiting for the check that runs every few seconds on its own. Roof state is what decides wet, sheltered and snow buildup, so this is the companion to snow when a build's cover looks wrong. Needs devcommands and runs host-side.

Cheat commands need the console enabled with the -console launch option, then devcommands typed once. They work in singleplayer or when you host, not on dedicated servers.

Without a number the command does nothing, though the number itself is ignored.
