Version 0.0.1

Cleanup and refactor in preparation for the first production release on Toolforge.

• removed libraries and code that we are not planning to use (should fix the problem with uberjar builds on Windows and macOS)
• refactored the get-pagepile functionality to reduce code duplication and improve architecture
• added the option to customize some settings using environment variables
• stopped using some deprecated hiccup functions
• fixed a few bugs
• added support for Docker/Podman containers (updated the Dockerfile)
• added support for Toolforge Build Service (by adding the Procfile and project.clj)

This request will be merged to main (in addition to develop) and will constitute release 0.0.1.
