Multi-color mode!

Ever wanted to increase your coloring skills with the ability to do more than green? Well now you can! With this new update you can colour the world in the primary colours (including cymk colours) to make your drawings just a bit better! Also this updates introduces some minor bug fixes on the server side, improves optimisation by not running 2 seperate world instances (had to before because i stupidly seperated the client world and server world meaning both had to exist for sync to happen) and yeah settings save and there is a controls graphic to help you learn those controls!
