Build 181020

As the game becomes very arcade at times, and already features things like dashes and slow motion, why not have another hack-and-slash feature here? The "perfect evade" or "perfect block" is now here as well, and dodging a projectile that is right about to hit you activates a brief time of slow motion action and destroys all the bullets within some range.

• Added the "perfect evade" feature.
• New console command: UPTIME. Can be either used to view the playtime, or, if input with an "on" or "off" argument, to display the counter on the MFD.
