Title: Add PrefixFilter to Scanner

I added a PrefixFilter to the API for the Scanner object using the HBase implementation of PrefixFilter. We use a lot of PrefixFilters in our work due to using binary rowkeys much of the time.

I also set the filter to set the startkey to the prefix to avoid scanning the entire table.
