Balance changes

After feedback that the game is too slow paced and complains about reloading - I've done some modifications to hopefully make the player feel a little stronger and make reloading less intrusive.

-start mag size 20 -> 30

-reload time 2.5 -> 1.7

-move speed 500 ->630

-base shoot speed .2 -> .17

-amount of enemies from 3 x wave to 4 x wave

-base bomb damage +2

-base bullet range (seconds until expire) 1.2 + (0.2 * range_level) -> 1.35 + (0.2 * range_level)

-reduce amount of cookies dropped, at a certain point you just have unlimited cookies
