New beta version for people to try.

Changes:

1. Add 'Relationships' metadata. There are 6 sites that actually present that data (AO3, checkmated.com, national-library.net, ncisfic.com, ncisfiction.com and prisonbreakfic.net) and another 13 that the 'ship is implicit and included by default.
2. Add extracategories, extragenres, extracharacters, extraships and extrawarnings configuration parameters. These are mostly to move the implicit categories, etc out of code and into configuration, but they can be used by end users to add/remove implicit settings. (IE, www.harrypotterfanfiction.com doesn't tag every story 'Harry Potter', so we add it. But now we add it in the ini file instead of in the code.)

These features, especially moving the implicit categories, etc out of code and into configuration touch a lot of files--53 of the 72 site adapters, in fact.

So I'd appreciate to hear how it's working--both good and bad.

Thanks.
