Scoring, Spawning adjustments, more custom sprites and animations!!!

Tonight we addressed the matter of achieving a score and displaying it. I'm going to be working on a backend api to house the scores but thats for later. We've also added 2 new custom sprites for the enemies and they're animated along with the ship!!!

I've also updated the way and rate at which enemies spawn, some spawn quicker depending on how long your run has lasted. It will be adjusted further. There are also some spawns that happen at point thresholds.
