Maybe speed up search

For investigative purposes, I'm bringing back James' original idea of removing naco_normalize (now spelled search_normalize) from the left side of the comparison.

In order to support this we need to apply all normalizers to the value column in the field entry tables.  That's done in a straight-forward way be just pushing the data into the column at the appropriate time in the appropriate trigger.  There is a small loss of accuracy, because some fields don't get that normalizations when being stored, but the user-supplied value will still be normalized.  But, these are just for relevance adjustment and not matching, so it's not too bad IMO.

Next, we make QueryParser forget about applying search_normalize to the column (but still to the value).

Testing appreciated! (basically untested at this point)

You'll need to rewrite the the field entry tables.  The following should be enough:

UPDATE metabib.author_field_entry SET id = id;
UPDATE metabib.title_field_entry SET id = id;
UPDATE metabib.subject_field_entry SET id = id;
UPDATE metabib.series_field_entry SET id = id;
UPDATE metabib.keyword_field_entry SET id = id;
UPDATE metabib.identifier_field_entry SET id = id;
