New massive uiZ overhaul

Although you might not notice it directly if you've looked over the old one, a lot has changed under the hood.

I've changed uiZ in such a way that things that don't need to be redrawn aren't redrawn every step. This means hugely improved performance.

Besides that, there have been major testing and bug hunting applied to uiZ. Every single object has been tested to work with a different configuration of parameters. With this, all objects are also overhauled. I'm still working on my documentation, which is why it still may take a while for this to upgrade.
