Implement enhanced Ticket support:
Tickets are a mechanism to allow for the "out-of-order" execution of transactions on the XRP Ledger. This commit, if merged, reworks the existing support for tickets and introduces support for 'ticket batching', completing the feature set needed for tickets. The code is gated under the newly-introduced `TicketBatch` amendment and the `Tickets` amendment, which is not presently active on the network, is being removed. The specification for this change can be found at: https://github.com/xrp-community/standards-drafts/issues/16
