Title: Map-Reduce on a secondary, for output into "local"

This patch allows for running map-reduce jobs on a secondary server in a replica set, provided that we are outputting into the local database. In order to make this work I also had to make the renameCollection command work for local -> local renames.

PS: Should JIRA issues be opened for all pull requests?
