Bugs and Health Bars

Mostly worked on fixing bugs tonight (UI stuff, some weird controls glitches, race position issues when cars were destroyed) but also finally added UI for health bars over cars. Makes it a lost easier to figure out who to take down now.

I also rearranged some of the way health works on cars to simplify it and centralized some of the car data so it's easier to access it from other scripts and other boring things like that. Good progress tonight but not very exciting screen shot material.

I should be getting sound effects and music pretty soon from people helping me with that and I'm excited to get those in.

Going to work a bit on making some cool rocket effects next I think!
