Some were modified from original but can't be bothered to check which.
'backlight' is custom. Changed both PC/laptop i3blocks config to
reference new i3blocks-scripts location.
system: Fixed keyboard repeat rate for PC/laptop.
Git: Added amending commit and forcing push aliases.
i3: Changed '$mod+F[1-3]' mappings to just 'F[1-3]'.
Split set-from-git into 3 different files for each section and created a
script for common directory variables. Created separate folders for
PC/laptop configs.
