> This patch refactors all places where Nutch manipulates page scores, into a plugin-based
API. Using this API it's possible to implement different scoring algorithms. It is also much
easier to understand how scoring works.
> Multiple scoring plugins can be run in sequence, in a manner similar to URLFilters.
> Included is also an OPICScoringFilter plugin, which contains the current implementation
of the scoring algorithm. Together with the scoring API it provides a fully backward-compatible
scoring.
