#1249: Lucene / ImportantDocument boosting class does not work due to Lucene 4.1
update

Due to Lucene 4.1 changes in the API.
{{{
If you previously used Document.setBoost, you must now pre-multiply the
document boost into each Field.setBoost.
}}}
Applied on Lucene update but need some fix.
The class needs to loop over the xml to be indexed instead of the (now
empty) doc to properly compute the boost factor for the document. Then
boost could be applied to all fields using Field.setBoost instead of
Document.setBoost.
Also boost is always set to 1 https://github.com/geonetwork/core-
geonetwork/blob/master/web/src/main/java/org/fao/geonet/kernel/search/SearchManager.java#L1409
We need to avoid "java.lang.IllegalArgumentException: You cannot set an
index-time boost on an unindexed field, or one that omits norms".
