Map prototype update 9-12-2018

added a lot of things to the map,like collisions, transforming the map into a planet, created gravity that points towards center of the planet map, added special physics for the player to be able to move on the planet.

the problem that i had with these features is that they depend on each other and so whenever I added something it would cause problem for the other things, which meant that i had to rewrite a lot of the things so that everything works without any problem.

there is a lot logic that is involved in making these parts (like vectors and Quaternions), which made it a little difficult to implement the features.
