Powered pipe, based on jacob1's commits

2012-08-13T22:48:55Z

PSCN to turn on, NSCN to turn off, INST to reverse.

Differences from jacob1's commit include: flood fill function that
includes 1px diagonal pipes, powered/reversed state stored in tmp
instead of flags, sparks from PSCN/NSCN/INST always take effect the
following frame, single pixel pipe directions are a number from 0 to 7
so "if(coords)" does not check whether one is set (store another
"transfers according to 1px pipe direction" bit for reverse flow).

Add ptypes.enabled checks to a few more places

Use atan2 for LIGH angle calculations

2012-06-28T23:04:46Z

atan2 gives the actual angle (in the range -pi to pi). acos and asin just
give the principal value (in the range 0 to pi, or -pi/2 to pi/2)

Move INST flood fill into a separate function

2012-06-15T12:45:55Z

Since there were so many if statements for INST in flood_parts. Also, allow
INST inside walls to be sparked.
