[tiny fix] No screen flashing upon using wand

[ZaRR]

Upon hitting wall/enemy with wand the screen will flash a bit as intended but personally found it annoying.
Decided to disable it.

function wandzap() --only in this "wandzap" func, NOT the first "zap" since it's used in teleportation/etc.
   kts.FlashScreen() -- deleted this line to get rid of flashing.
