Title: MongoDBPurger should purge instead of drop

Dropping the collection drops everything (of course), including the indexes and capping information. The only "drawback" of removing instead of dropping is on capped collections, that don't allow manually removing items, but that's a MongoDB restriction ( http://www.mongodb.org/display/DOCS/Capped+Collections#CappedCollections-UsageandRestrictions ).
