teeworlds / teeworlds should have been always "Teeworlds and zlib",
because it bundles some md5 code which is zlib-licensed.
teeworlds-data was supposed to be CC-BY-SA, but it was not marked this way.
Now to the real changes, since 0.7 it bundles json-parser (unbundle
will come within next few days) which is BSD licensed, so teeworlds
(not -server) will have "and BSD". Once I will unbundle it, I will
remove this part again.
Thanks for attention!
