Mining mechs, which currently only spawn in secret asteroid rooms, no longer have tracking beacons

Changes to windoors.
- Secure windoors now require 2 plasteel sheets instead of 4 rods
- Windoors and secure windoors have reduced health.

Added checks for proximity, canmove and death on:
- Library scanner
- Library computer
- Library public computer
- Bookcases (Fixes issue 564.)
