Simplify map rot code.

Amnesia traps -- and thus, flat chance maprot -- is long since gone.

Of particular interest is the way old forget_map() was called from abyss.cc.
We had two functions:
    forget_map(bool force)
    forget_map(int chance = 100, bool = false)
Guess which one forget_map(true) called?  Not that obvious that one prototype
was missing...  No wonder no sane language has function overloading.
