gluon-config-mode-ppa: text of PPA should be included

[Adorfer]

Since at least a significant number of people will not have internet-connection on their browser while setting up the node (no other route...) it's not nice to force people to sign to rules they have no chance to read in person. (this may render the "acceptance" invalid.)

At the Moment, you are not forced to select the Box. You can continue without it.

But a good idea. Maybe a gzipped Version.
