Mapster32: Rudimentary support for auto-aligning along TROR nextwalls.

Browse source 
Usage: press the ['] (quote) modifier together with the PERIOD key.
Aligns only the immediate upper and lower neighbors of each wall that got
aligned by following point2s or nextwalls.  Doesn't play well with Alt
(carry over xrepeat) yet, might need two subsequent alignment passes.
