Finally add packages for the "new" version of blackbox, 0.70.x.
This window manager is incompatible with older versions, and older
add-on applications (aka "bbtools") will not work with this version.
Hence, add new versions of bbkeys and bbpager as well, to provide
at least the basics. (Again, these will not work with older versions.)
Why are we adding these? Well, I'm told that blackbox 0.70.x is
fully EWMH compliant and has better fonts. And people always ask
"why is blackbox 0.70.x not in pkgsrc?".
blackbox version 0.65 and the other bbtools that work with blackbox
will remain in pkgsrc.
