Copied i3blocks scripts from orig dir

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]'.
