Xyris 0.5 - Tengu

[Kfeavel]

Once again it's time for the yearly Xyris release. This time we've got a lot of foundational changes, but a couple of cool new features as well, like the addition of a proper framebuffer, complete with a font for text output.

• Rename from Panix to Xyris
• Add Scuba (Docker) support
• Add Github CI support
• Move documentation to Github pages
• Switch to using Limine bootloader
• Add generic bootloader information parsing
• Add kernel argument handling
• Framebuffer drawing and text printing
• Framebuffer double buffering (Thanks @Jmallone!)
• Improve kernel library (Ring buffer, linked list, bitsets)
• Improve kernel library time keeping (Thanks @Jmallone!)
• Improve kernel logging
• Add kernel library unit tests
• Convert all GAS assembly to NASM (Thanks @the-grue!)
• Convert boot assembly to C
• Increase architecture specific code separation
• Many other important organizational, architectural, and repository changes

Special thanks to @the-grue, @Jmallone, and @mauryafunez for your amazing contributions!
