Solid foundations

This release is a major rewrite of the script and gives a solid foundation for future improvement at the cost of some features.

It changes the interface of the wimp. Now the wimp doesn't live in the same directory as the script and now more than one wimp can exist on a single machine. The interface is now more in line with the systemd service nature of the wimp, allowing a user to check its status and restart it if something goes wrong.

It is no longer possible to use custom styling, however.
