Revision 904615

Thanks Filipe Manana. Closes COUCHDB-631.

Replicator option to replicate a list of docids (bypasses by_seq index).

Usage: POST to /_replicate with a JSON body of:

{"source": "myfoo",
"target" : "http://remotedb.com/theirfoo",
"doc_ids": ["foo1", "foo3", "foo666"]}

This will copy the listed docs from the source to the target database.
