Updates after players feedbacks — Big Byz Wars Steam update #1189747

- fixed assault rifle endless fire without a player click - fixed 'black squares' glitch during intense shooting - fixed shotgun impact 'on surface hit' (only 1 of 5+ bullets, for performance reasons) - performance optimization: texture max sizes reduced for different props - enemy location small adjustments - fixed 'Data Cell' dialog trigger position - fixed player kill NPC in 2d from a far distance (range limited to ~edge of the screen) - fixed NPS rifle/shotgun firing after AI death - hide shotgun crosshair between shoots (annoying chaotic move) - added slight camera shake for shotgun shooting
