This makes the filters similar to output options.
- Adds coherence to error messages.
- Enable aliases (used the ones suggested by @leoheck)
Additionally now the README.md preflights documentation comes directly
from --help-preflights
Now the options are just an attribute of the outputs.
It means we have a set of classes for the options.
All the output content is parsed by the classes, including the Layers.
Now the layers support a simple string (with interesting shortcuts), a list of
strings or the original list of dicts.
Now the legacy drill.map.type and drill.report.filename are specified in this
way.
The BaseOutput class now inherits from Optionable.
Suboptions are just Optionable classes.
Also: added traceback print when an error is reported and we are in debug mode.
They can be added from ~/.config/kiplot/plugins/
Also sorted the preflights in the YAML example and allower -v for
--help-list-outputs, needed to know from where are the plugins loaded.
The old mechanism is supported, but removed from examples.
Added a test case for the new mechanism.
Documented the reason for the complex properties.
Added docstrings to these particular cases (with None as default).
