Update NAB to Python 3 (numenta#353)

* Convert NAB and most detectors to Python 3
* Refactor remaining Python 2 dependant detectors.
 - Move twitterADVec documentation and script from wiki+gist to repository.
* Update main README.md to reflect changes following NAB port
* Disambiguate -d, --detect, and --detectors by readding --detect argument (See: numenta#346)
* Remove duplicate files from htmjava detector dir
* add plot and build, dist to gitignore
* NAB: py2 numenta detector: update install instructions
* Add executable bit to gradlew
* Reduce problematic wait time value in runner.py scripts
* Added RCF runtime to list of offline detectors.
* Fixed versions, added CHANGELOG
* Specify python 3.7
