re-applied from 13abc23c:
- remove zdoomism from backpack secret's door
- fix pegging on armour secret's door's tracks
- remove several unnecessary linedef and sector tags
Also make the chainsaw secret less obvious, by making linedef 2654
secret. There is already a subtle visual hint (look at the bottom
of the wall)

- make teleporter exit point thing 11 in sector 116 exist on all skill
levels, so the final chaingunner for the blue key trap can teleport
- make it harder to get the blue key without triggering the trap, by
copying the trigger on linedef 941 to linedef 641 as well
- change specials of linedefs 2168 and 2170 to be manual, so the door
can be opened without relying on implicit manual zero tag behaviour
- make the slime alcoves in the yellow key corridor damage the player
- set lower-unpegging flag on doortracks for the armour secret and the
blue key door (sectors 247, 374; linedefs 1472, 1475, 2176, 2182)
- remove unnecessary tag 46 from sector 46 and its surrounding linedefs,
since the door is a manual one.
- remove unused sector tag from linedefs 154 and 168
"Trivial" meaning only object properties changed, not references, so a
small diff and no nodebuild required.
