Merge pull request #156 from SenseiKiwi/master

Fixed Golden Door Item ID Mishandling
Minor Change

Minor change to a line in CustomLimboPopulator. We should access static
fields through their classes, not instances.
Fixed Door Render
Overhauled Monoliths

subdivided more clearly now. The aggro level is sent over a data watcher
instead of sending the texture state.
