cleaned up subquery model matching check
fix bad subquery redis_prefixes
change query redis_prefix to use module-less model class name
(old: Rails:Foo:Queris:Queris::ActiveRecordQuery: , new: Rails:Foo:Queris:ActiveRecordQuery:)
clear query existence data when flushing, just in case.
hopefully fix for unexpectedly stringy results_keys
fixed clear_queries! to really clear all queries
version bump
better rake load_all_models code
