Create Player Controller (#4)

Browse Source 
* add player scene

* add some logic to control player velocity

* add debug scene and reset main scene

* add sun and env to debug scene; fix normalization of movement

* add kenney WIP assets for debug

* fix movement further and add jump

* add mouse camera control

* add sprinting

* add crouching

* use constants for height

* try to improve crouching by checking to see if there is a collision above before un-crouching

* update README about line width

* move test cube in front of playercontroller
