issue2550653: xapian search, stemming is not working
This is a partial fix for the issue. It does make stemming work
(so searching for silent will also return docs with silently in
them). However to do this we need to lowercase the text so the
porter stemmer will work. This means capitalization is not
preserved.
Tests in test/test_indexer for xapian backend all pass.
David Wolever (wolever) did the work.
