Minor changes to aid compilation.

Removed all the unneeded placeholder patches.
Removed Ancient tiletypes holdover.
No real ambition to make a fastdwarf edition for mode 1 for everyone.
Thus deleted fastdwarf2.cpp
autolabor.cpp changes to autolabor2.cpp. Used Handle Vehicle 'weights'

No research yet attempted to fix 5forbiddenunlock to make it _work_.
