New patch based on the discussion on lucene-dev (intermediate version)
According to my understanding of our dev-lucene discussion Multisearcher should
evaluate queries in the following way:
1. rewrite queries using the Multisearch Similarity
2. extract necessary terms
3. collect idfs for these terms from the Searchables
4. adjust query boosts according to collected idfs
5. distribute re-written and re-boosted query to Searchables
6. merge results
This patch implements all steps except 4, where it uses a modified Similarity
class instead. Thus it is fully functional, but not yet ready for commit.
