Hotfix 1.1.1

This hotfix is aimed for fixing bugs related to new RPG mode, balancing weapons and game logic for more funny and challenging experience.

RPG mode changes:

Because original system was too realistic, future update aimed and game-values-changing friendly, it got too buggy.

Because there is no difficulty settings and no need to make game realistic, enemy flight got turned from calculated trajectory into simple animation with same look but more CPU friending. And now enemies can't survive collision with rocket and explosion.

Because of that enemy health multiplier was deactivated.

Balance changes:

Machine gun - reloading time was increased from 2.5 seconds to 5.

Shotgun - pellet scatter was decreased in about 2.5 times to not allow players cover all map with a single shot. Pellet damage got 2 times lower and amount of pellets got reduced from 30 to 25. But reloading got faster - from 2.5s per shot to 2.0s.
