added the ability to bypass the downcasing of fulltext queries

[jmphilbrick]

The fulltext method currently downcases every query passed to it. This prevented the ability of doing an exact match of a value with mixed case in a solr query:

column_name:"Some Mixed Cased Text"

This is actually done on purpose. All of the text is run through a lower-case filter in order to make all searches case-insensitive. If you don't downcase the query, you won't find anything. Is there a specific case you're trying to address? Or is there somewhere something isn't working?
