Add own keymap; Fix formatting error in another person's layout

[jmarmstrong1207]

Add my own keymap. Adds a magic FN1 key for caps lock, media player buttons for v,b,n in FN2, and a numpad in FN2. In addition, I fixed a formatting error in the second file requesting a pull request.

It also involves removing whitespace at the end of some lines, but that was from my VSCode's automatic formatting. Don't think it'll be much of an issue though.
