Refactor config file API.

The config file API previously relied on binding config variables
using M_BindVariable() which took a void pointer. It occurred to me
that if used on a boolean variable, this would be erroneous, but the
void pointer would make it impossible to tell. Split this into
separate M_Bind{Foo}Variable() functions based on type, which allows
for proper type checking on the pointers that are passed.

Vaguely related to #509.
