New art. Fixed issues with snipers and tanks. Added particle effect for flags.
* Fixed issue where snipers lost shots/reload by quadruple/triple shooting one unit when they could've just shot some other unit (fixed this for the most part)
* Fixed issue where tanks no longer did splash damage
* Made the game look prettier with a NEW BASE!
* Made it more obvious to know when a flag got captured by displaying a particle effect. Also changed the color of the +1 number above the flag to indicate that it got captured by the respective team. Aliens would be purple, humans would be green!
