Reduce amount of re-renders for a Node

[UZ9]

Because of dependency requirements changing in real-time, a Node ends up re-rendering itself 6 times when initially clicked. This is obviously not ideal, and some of these dependencies should be bulk initialized in one pass if possible.

Another change to make is to stop the grid visualization vertex and fragment shaders from being loaded individually for each node. These should instead be in a class similar to materials.js.
