Title: Upgrade to Lucene 4.6.1

This upgrade includes a fix for RAM estimation on IndexReader
that allows to expose the amount of used bytes per segment now
as a setting in Elasticsearch. (LUCENE-5373)

Additionally this bugfix release contained a small fix for highlighting
that was already ported to Elasticsearch when reported (LUCENE-5361)

Closes #4897
