fixed a bug in the find_all_by_ids method where we were increasing the page index when we shouldn't have been so anything beyond the first group of 10 wasn't being returned.  YGL removed that limit on 10 at a time, so we are going to bump this to 20 ids at a time
bumped version for a new release with httparty ~> 0.10 and mash ~> 0.4 (hashie ~> 2.0)
