laser tag modded

changes I've made - fixed hit detection (I hope) - altered some gun stats & sounds - added targets around the map for you to shoot when you're alone, they give no points and disappear when more than 1 player is ingame - added headshots and related visuals & sounds - spruced up game UI a bit (added animations to score UI and made elimination text fancier) - added a visual on the reticle for eliminations - made TDM code responsible for adding & removing teams, so other modes with no teams or different amounts of teams can be added without issue
