Use of a slang expressions should be avoided in readthedocs

[DennisClark]

The unexpected term “sausage” can be found at
https://vulnerablecode.readthedocs.io/en/latest/tutorial_add_new_importer.html
and we should avoid terms that could be mis-interpreted

A lot of internal sausage about importers could be found inside

There is a similar problem at
https://vulnerablecode.readthedocs.io/en/latest/tutorial_add_new_improver.html

perhaps discussion would be a better word here than sausage.
