Operations without query are showed again.

They were hidden after commit 5bec98da873ad53ffa58fc27020eeee71e0e2d41.
Checks added for optime keys on the replica set output.

I hope this fixes #2 optimeData KeyError on an unknown version of MongoDB or Pymongo.
Address of source which is not in the block is showed on the replication status block.
Version updated to 1.3.
