Chapps

- Correcting dependency misalignments in setup.cfg which were preventing
CHAPPS from launching after installation from PyPI

- Massive documentation update, using rST and Sphinx

- Some minor code cleanup, mainly removing completely extraneous code

- logic added to `VenvDetector` to detect when the library is launched
by Sphinx; depends on code added to `docs/source/conf.py`

- CHAPPS now defaults looking for its config in its venv by default if
one is being used. (`<venv>/etc/chapps.ini`)

- CHAPPS does not attempt to write a config file when invoked by Sphinx

- Corrected missing statements which caused new email tables not to be
created by `chapps_database_init.py`

- added more acknowledgements to INSTALLATION

- added whole-email matching related docs to README.md

- Corrected incorrect homepage URL in setup.py

- Polish documentation.

- Added full-email auth to SDA module.

- Added full-email auth object CRUD routes to API.

- Changes to signature of route path for association-list management:
routes are now named for the association and use GET/PUT/DELETE

- Add full-email checking cache maintenance routines to Live API

- Live routes for bulk peeking and clearing of Redis cache now
accept lists of both domain IDs and email IDs, and if both are
provided, will provide all the output combined in a single dict.

- Correct error preventing automatic table building by provided
setup script.

- Provide better documentation about setting up the database.

- Minor adjustments to API README

- Paginate associated objects
(paginate domains for users, and users for domains)

- Adjusting location of API README to correct bug preventing API launch

- Adding VenvDetector util class, to help find API README after installation

- Adding CHANGELOG to PyPI package

- Add a little extra documentation about **syslog** message configuration

- Improved Swagger/OpenAPI documentation. Handling assignment of
path closure docstrings explicitly fixes the problem. Various
formatting improvements have also been included.
