The move to using auto-formatter makes it easier to read, submit and
speeds up development time. https://github.com/ambv/black/
Although I would prefer 79 chars, the default line length of 88 chars
used by black suffices. The flake8 line length remains at 120 chars
since black does not touch comments or docstrings and this will require
another round of fixes.
The only black setting that is not standard is the use of double-quotes
for strings so disabled any formatting of these. Note however that
flake8 will still flag usage of double-quotes. I may change my mind on
double vs single quotes but for now leave them.
A new pyproject.toml file has been created for black configuration.
Use a sha1 of time.time() can result in identical host_id. This was
evident with Travis tests randomly failing due to host_id collision
returning the wrong host details.
Using uuid4 to generate a random UUID in hex form should fix this issue.
* Add host Edit button to WebUI.
* Updated and fixed associated tests.
* Refactored related gtkui code to better understand code flow.
* Removed dead code in gtkui.
