Added JSON model for floor "quad"

Fades in and out with rotation, which I'm pretty sure should not be
happening, but at least it's there. Set a dimension for the camera so it
does not zoom in and out when choose a new renderable. Renderables still
in center position on top of each other. Will eventually take out the
check boxes for static scene.
Update on Renderables and Quad

Working on getting more than one of a particular model to be translated
each time another instance of it is in the activeModels array. Basically
working out positions of the models still. Good enough for a push. Quad
Fades in and out for some reason....
