Feature/regex tag

[rolandmueller]

This feature would introduce the TAG element as a module. Needs a new parser for the SpaCy translate.
Would allow more flexible matching of detailed part-of-speech tag, like all adjectives or nouns: TAG("^NN|^JJ").

Looks nice! just need one test to keep coverage and some minor lint stuff (doing flake8 locally, exclude parsetab: --exclude=rita/parsetab.py because it's generated file and fails most of the rules)
