Revert "Doors: Remove ..." and "Doors: Allow the screwdriver to ..."

This reverts commit 5e4a6e8a, and
             commit 60cf3f85.

The original door API rewrite I posted had all rotation disabled using
the correct on_rotate() handler returning `false`. Two subsequent
changes attempting first to enable simple rotation and second disabling
that again changed the callback handler to a boolean `false`, which
is incorrect use in the screwdriver API, and actually allows rotation.

The proper way to disable rotation for facedir nodes it to use a full
callback handler that does `return false`.
