Problem: filetype: skhd files are not recognized
Solution: Detect .skhdrc and skhdrc as skhd filetype,
include a syntax and filetype plugin, add syntax tests
(Kiyoon Kim)
Add syntax highlighting for skhd (simple hotkey daemon for macOS)
configuration files. Includes filetype detection for skhdrc and
.skhdrc files.
