Build v0.015b — seamless server travel

The big one here is seamless server travel with inventory — the squad can move between levels without the session dropping and without anyone losing what they were carrying. A fair amount of this build is the supporting work and the small fixes that came out of testing it.

The AI senses fix

One line, disproportionate impact: setting bAutoRegisterAllPawnsAsSources=false gave, as the changelog puts it, “(ALOT) better AI senses with alot of zombies”.

When every pawn registers itself as a perception source, the cost scales badly with crowd size — which is a problem in a game whose entire premise is crowd size. Hearing and damage senses on zombies were fixed in the same pass.
