let the user choose background color for newline module

[rockandska]

Let the user too chose the background color for newline module.
Useful if you have a module who fill the wall line like mine (see bellow)

Without the modification:

With this modification :

I don't experience the issues with the background color as shown in your first screenshot.
Is this caused by the changes made in PR #11 ?

I think it is not related.

But before provide you a test case, see this bug not related with the test i will provide you just to be sure that is not my module who include it

Don't know why , but the line is clutter

Now, concerning adding the possibility to the user to define the background.
Add a module to fill the line :

function fillps1 {
       local bg_color=$1                  # Set the background color
       local fg_color=$2                  # Set the foregropund color
       PS1="${colors[${fg_color}]}${colors[On_${bg_color}]}$(printf "%$((${COLUMNS:=$(tput cols)} - 1))s")${colors[${bg_color}]}${colors['On_Default']}${symbols[hard_separator]}\e[0m\033[0G${PS1}"
       unset __last_color
}

You will get the same as my previous screenshot
