OPENNLP-547: Add a transition-based dependency parser

Add an arc-standard dependency parser with maxent and perceptron training,
model persistence, and an immutable dependency graph. Skip and count
non-projective training sentences.

Read UTF-8 CoNLL-U samples with universal or language-specific POS tags.
Add CLI tools for training, parsing, evaluation and cross-validation,
including attachment scores, evaluation listeners and -misclassified
output.

Add treebank evaluations for English, German, Spanish and French, and a
manual chapter with tested examples.
