Resolve license information inconsistency

Although the addition of "version 3 or later" to the README [1] predates the
commit that added LICENSE.txt with the description "LGPLv3 for code" [2]
I think it's safe to go with the latter since the terms were clarified
again by the original author explicitly without the "or later" clause [3].
closes #575
