Alphabetises letter component in book/vendor

About the PR

Adds a 1 second delay to mechcomp teleporters activating. This is my first time introducing a SPAWN_DBG so hopefully it's in the right spot.

This PR moves the letter display's position in the mechcomp book and vendor under the LED component because as a general rule both of those are alphabetised.

Why's this needed?

I like it, but using Spawn would make the period take longer when the game was lagging. maybe use action bar timers instead?
and if it was visually represented with a bar I think you could take the 'charge up' time lower to like 0.5 seconds since it wouldn't trigger on people running over it and would very quickly trigger if they stood still.

I've let this PR sit for a bit to see what reactions it gets, but surprisingly next to no-one in the thread likes the delay.

I'd look into the action bar thing, but with the response I'll probably instead soon remove the delay thing again and leave putting the letter component in the right spot.
