Major Description
There was discussion a long while back about eliminating the plethora of CHANGES.txt files in various lucene contribs/modules and consolidating into lucene/CHANGES.txt to prevent "hiding" things from users who may not know/think/remember to check each of the individual contirbs/modules.
this is long done and dealt with under "lucene/", but on the "solr/" side we still have a multitude of CHANGES.txt files in contribs that are inconsistently used to record features/fixes in those contribs (frequently they get listed in solr/CHANGES.txt instead)
We should eliminate these contrib/*/CHANGES.txt files completely, and merge all of the existing items in them into the apropriate version & section of solr/CHANGES.txt
