Version 3.1.0

• Grammar normalized and enhanced. This may cause parse trees to be slightly different from previous versions. For example the phrase "í dag" no longer appears as a single tree node with a multi-word adverbial phrase, but instead as a temporal phrase subtree with preposition and noun nodes. Also, verb phrases are expanded into nested subtrees in a more consistent manner than before.
• Configuration files cleaned up as a consequence of the split-off of BinPackage.
