Sight Blaster and other skill fixes, magic reflect, crash, trap display and monster behavior fixes

- Fixed cast time of Sightrasher in pre-renewal (700ms -> 500ms)
- Official Sight Blaster behavior (bugreport:6945, partially bugreport:144)
  * Sight Blaster's AoE is now 3x3 even in pre-renewal (it was originally larger so it hits traps before they trigger)
  * Sight Blaster will now prevent traps from triggering as long as they are knocked back
  * Fixed a bug that caused Sight Blaster to not work on traps and ice walls at all
  * Sight Blaster will no longer expire when the attack was reflected
  * Sight Blaster will now expire when hitting an ice wall
  * Sight Blaster will now properly protect you from being attacked from its AoE range
- Sight, Ruwach and Sight Blaster will now check for a target every 20ms (previously every 250ms)
- Step action will now be canceled when being knocked back (skills won't be executed anymore when knocked out of range)
- When knock back magic is reflected it will no longer lead to the caster being knocked back (related to bugreport:6945)
- Activated traps can no longer be hit
- Fixed a problem that left "trap ghosts" forever on the screen when a trap was knocked out of the screen
- Monster behavior fixes
  * Monsters will no longer be able to do normal attacks when hiding
  * If out of any reason a monster on "attack" state can't move and can't do normal attacks, it will now use "attack" state skills
  * The order of monster thought processing is now equal to official servers
- Fixed some potential map server crashes
