Impossible to set graffiti with spaces

[pepawel]

If Vitalik went back in time and used Stereum to create the first block, then instead of "Mr F was here" the graffiti would be "Mr" ;-)

This is caused by bash. My bash skills are limited, so I failed at fixing this issue.

The problem appears to be located here:

  ansible-playbook \
    -e e2dc_graffiti_updated="$choice_graffiti" \
    -v \
    "${e2a_install_path}/set-graffiti.yaml" \
    > /dev/null 2>&1

The fix should allow to to use spaces, single and double quotes, as well as backslashes and other special characters.
It would be nice if it works for unicode characters, so one can use famous "🐠Welcome to the New Beginning" graffiti :)

I haven't checked if the problem affects also web version of control center.
