[mojosetup] Patch to enable skip the confirmation of the EULA

[Jeremy White]

> Thanks, this is now in revision control!

That was a horrible mistake; now I'm encouraged to send the next batch,
and they're worse <evil grin>.

I will state in advance that I don't know gtk, or lua, or, really,
mojosetup, so I won't be hurt if you need to point out horrid flaws in
any code submitted.

I similarly won't be hurt if you feel a patch is too specific to our
needs and not generally useful to the project.

Cheers,

Jeremy
