This is another cleanup as a result of pydoctor gaining a warning, this time about the same parameter being documented more than once.

There were three categories of mistakes found by this warning:

• actual duplicate documentation for the same parameter
• non-duplicate documentation accidentally using the name of another parameter
• fields where @type was intended instead of @param
