[Pharo-project] Changes in MongoTalk

I've introduced the notion of limit to the MongoTalk driver (see the MongoTalk repo). If someone (Nico, Esteban?) could have a look at the changes it would be great. The test case is overly simplistic but it should illustrate the point. Next on my list: numberToSkip[1]. With "limit" and "numberToSkip", we should be able to have something like pagination easily. Please stop me if none of these changes makes sense ;) [1] http://www.mongodb.org/display/DOCS/Mongo+Wire+Protocol#MongoWireProtocol-OP...
