Merge branch 'multi-database-support'
This is a backwards-compatible way of making most of functions in monger.collection and monger.gridfs support explicitly passed database objects. In some cases we cannot do that because of Clojure compiler limitations on # of arities each function can have. For those cases, see monger.core/with-db, monger.core/with-grifs and so on. Fixes #4.
