Changing color of default red 'set colorcolumn=80' #28

The red bar from set colorcolumn=80 is somewhat distracting and does not fit with the airline theme.

I propose implementing a soft and hard line wrap using a gray color scale color as an alternative.

let &colorcolumn=join(range(81,999),",")
highlight ColorColumn ctermbf=235 guibg=#2c2d27
let &colorcolumn="80,".join(range(120,999),",")
