Restructure network stack to use new Interrupt methods instead of hard-coded IRQ numbers. Add line count update into build process. Add progress bars to HTML generation and DoDistro. Clear Network Log border_doc. Fix font chars. Clean up some lingering unconverted variable and directory names. Remove word-wrap DolDoc tag from Clementine bible because of CPU spikes.
