Sofie 46dfe773e1 Replacing regex library with re to increase tokenization speed (#3218)
* replace unicode categories with raw list of code points

* simplifying ranges

* fixing variable length quotes

* removing redundant regular expression

* small cleanup of regexp notations

* quotes and alpha as ranges instead of alterations

* removed most regexp dependencies and features

* exponential backtracking - unit tests

* rewrote expression with pathological backtracking

* disabling double hyphen tests for now

* test additional variants of repeating punctuation

* remove regex and redundant backslashes from load_reddit script

* small typo fixes

* disable double punctuation test for russian

* clean up old comments

* format block code

* final cleanup

* naming consistency

* french strings as unicode for python 2 support

* french regular expression case insensitive
