The existing approach had some issues with how the control-chars were escaped; also switching to use Dockerfile here-doc to make it a bit more readable, and add some comments to the `.bashrc`. Also make sure the MOTD isn't printed multiple times, and only for interactive shells, and slightly tweak it with some colors. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
