Tile:
-	Now uses ELEMENT_ARRAY_BUFFER (which all models should be using
	anyways)
-	Actually works!
-	Tiles now have a colorBuffer that can be set. Useful for certain
	shaders such as the outline shader

_x:
-	Made a small 2D Tile array for displaying a simple grid of Tiles

ClieantResources:
-	Added a few resource files for shader stuff

simple_colors.vs:
-	A simple vertex shader that accepts a color buffer and vertex
	positions

simple_colors.fs:
-	A simple fragment shader that accepts a color and vertex positions

simple_outline.fs
-	A fragment shader that uses the color attribute to paint on a black
	border over any pixels that have a very low green value

NOTES:
vertex shaders will have the .vs suffix and fragment shaders the .fs
suffix. Any objections?
