Miniboa

This release fixes provides a method to specify the encoding for your `TelnetServer`. By default it will still use `cp1252`.

To use `utf-8`, you must provide it in the constructor as so: `TelnetServer(encoding='utf-8')`

Python 3.7 support and ANSI escape sequence fix
Added Python 3.7 to trove classifiers

Thanks hroncok cjmayo Tizen

This gets rid of the old cp1252 handling, and we just use utf-8.

This might have some people yelling (at some point) for romantic historical masturbatory reasons. Let's find out

Fixed spacing to get pyflake passing

There was a renaming of many methods in one fork of miniboa, and through error I never originally published a fully working miniboa because of this inconsistency.

It would always hard error if the client sent a 3 byte command (such as ^c). Fixed now!

Also there was the issue with flake8 dropping Python 2.6 support. To remedy, we just use pyflakes and pycodestyle (pep8) now.

In Version 1.0.0 there is a passing test, pep8, linter, and complexity testing. Also backwards compatibility with Python 2.
