Added color profile for tilix terminal

[emirror-de]

An initial version of the papercolor theme for tilix has been added.

The following parameter have not been edited to match them to the other colors, they have been simply copied from this example:

• highlight-foreground-color
• highlight-background-color
• cursor-foreground-color
• cursor-background-color

The badge color has been copied from the "gnome-terminal" light theme parameter "bold_color".
