Upgrade to released mongod 1.4.0
Ensure that oplog observe driver retries on error
Bump openssl version used for mongo. Add node-aes-gcm.

The previous version of openssl (1.0.1f) was vulnerable to the 'heartbleed'
attack, though Meteor did not use this version in a way that opened
it to attack. The build of openssl here is used only for mongod, not
node, and was used only as a client, not a server. But lets upgrade anyway.
