[SPACE][+] Added code basic code behaviour for moving forward, rotating to point and stabilizing yourself

[SPACE][#] Can lock the camera
[SPACE][#] Moved ShipEngine update to FixedUpdate to fix physics issues
[SPACE][#] Made AdvanceTo use max force to minimize time. Involved writing a mathfunction class that can handle segments
[SPACE][#] Updated scene
[SPACE][#] Switched over to 2D physics - elimantes weird rotation

[SPACE][!] Fixed AdvanceTo by considering the fact that the FixedUpdate is not necessairly called at fixed intervals
