Stop parameter parsing if no matching alias

If we encounter a potential alias parameter like @author but have no alias entry, it would be nice if we could just interpret that line as a standard non-parameter line if possible.

Should be very easy to ignore such invalid parameters, issuing a warning about them to the log.

Hmpf. I am not sure that it is worth complicating and uglifying the otherwise beautiful design just for an invalid use case (@author makes a lot of sense for JavaDoc, but JavaDoc makes no sense with scripts).

I mean, yes, we can now go on and have a lengthy discussion about the merits and the downsides etc etc, but should we not perform some useful biological research instead?

If we go my route of a getCommentStyle and use EOL comment styles for that (e.g.: // for Java) then the "Javadoc" use case problem goes away.

We probably need to make that change anyway, to avoid other overly aggressive parsing situations. This problem will keep rearing its head in various forms until we fine tune things.
