- standardize the documentation in my config files
- Removed all the unused/unneeded feature .c/.h files (including RGBmatrix)
- now that I think I have my featureset set, I consolidated my rules.mk to
lessen the 'include if' commands
- added more clarity on which files have config to each rules.mk
- enabled encoder on swoop again
- removed rollow oled config/files because default is fine
- added some keycodes back because I forgot not all keyboards have encoders
- added common oled config
