Parameter input

[evesala]

It would be handy if I could change the input parameters (or the resultPattern) of a generator plugin instance. Ideally so that I would have to install a generator only once, but could then have different blog posts calling the same generator with different parameters. (In practice this would mean specifying different subtables.)

For example one blog entry could discuss the actors of a dungeon generator, calling {dungeon#actor}. Another blog post could discuss the locations, and the example would call {dungeon#location}.

This would be useful also for debugging.
