* Add pos and morph scoring to Scorer Add pos, morph, and morph_per_type to `Scorer`. Report pos and morph accuracy in `spacy evaluate`. * Update morphologizer for v3 * switch to tagger-based morphologizer * use `spacy.HashCharEmbedCNN` for morphologizer defaults * add `Doc.is_morphed` flag * Add morphologizer to train CLI * Add basic morphologizer pipeline tests * Add simple morphologizer training example * Remove subword_features from CharEmbed models Remove `subword_features` argument from `spacy.HashCharEmbedCNN.v1` and `spacy.HashCharEmbedBiLSTM.v1` since in these cases `subword_features` is always `False`. * Rename setting in morphologizer example Use `with_pos_tags` instead of `without_pos_tags`. * Fix kwargs for spacy.HashCharEmbedBiLSTM.v1 * Remove defaults for spacy.HashCharEmbedBiLSTM.v1 Remove default `nM/nC` for `spacy.HashCharEmbedBiLSTM.v1`. * Set random seed for textcat overfitting test
