Title: Removed spurious 'a' in documentation.

There was an extra, unwanted 'a' in the documentation on arbiters in replica sets. The extra 'a' looks pretty benign in the source code, but generates an extra paragraph with a lonely 'a' in the [online documentation](http://docs.mongodb.org/manual/core/replica-set-members/#arbiter).
