Based on more feedback I've cranked up the spawn rates of AI vehicles and civilians so streets feel more "full".

VERSION: 0.4.30 - 03/09/17
====================
- [Feature] - Added Difficulty settings. Easy Mode now gives you 1.4x damage dealt and 0.6x damage received, medium gives 1.2x damage dealt and 0.8x damage received, Hard gives no bonuses. Medium is now the default difficulty. You choose the difficulty whenever you start a game or load a game.

- [Misc] - Spawn rates of civilian vehicles increased (from 15 to 24), spawn rates of civilians increased (from 7 to 24). CDF spawn rates reduced. This is so streets feel less "empty"
