Fix game code that makes false boolean assumptions.

Various bits of code assume that booleans are represented as 32-bit
ints and that they can be assigned to from 32-bit values. This isn't
true on all systems; fix code that does this to convert to boolean
values properly.

This is more progress towards fixing #509.
