Transactions

Hey @rcrichton and @devcritter. Ive made some changes to the transactions console to accommodate for the rerun transactions. When you have a moment do you mind just reviewing this. In the listing i've added an indicator to show a record is a rerun and on the detail view page a list of the rerun transactions can be viewed if you viewing the original transaction. This works with the core changes which i will pull soon. Thanks
Yeah that does make sense. We shouldn't ever got transactions re-run that much. But, I still think we should avoid using an arbitrary number. Rather us a limit of 0 - that is the same as not applying any limit: http://docs.mongodb.org/manual/reference/method/cursor.limit/#negative-values
