Fix typo on uppercase.
Update docstring for Parameters.parse.

As pointed out in issue #10, it was not very clear what the parse method
was doing.  This new docstring should rectify that but a readability
expert should really let loose on all of the documentation we have.
Update setuptools to 5.3.
Reduce setuptools requirement to 2.2.
Drop monkey patch and build on python-2.7.

This should fix #11
Make pyinotify an extra requirement.

Also switch to using the pip requirements parser in setup.py.
Fix typo in test requirements.
Remove unicode from README.
Bump version: 1.2.0 → 1.2.1
