Includes:
* new Transfer module
    * this will eventually replace the balances module transfer api
* contains update to bonsai transaction tracking
    * replaces the `store_uuid()` function with two new functions `start_tx()` and `end_tx()`
    * updates the orders module to use this new bonsai transaction tracking

The main change here is creating the escrow address and applying the payment to that address when locking funds. This should not therefore change the total issuance.

This update is a second major update to the code, amending the Substrate Standard to physically remove funds when funds are locked.

There is still some work to do to ensure that the mechanism is robust enough.

This is a major update to substrate standard balances module with the following enhancements. It also updates the version of Totem Meccano to v1.11.0.

* creation of an "accounting pallet" (replaces previous accounting modules)

* including "accounting pallet" in balances module

* calling a fee posting mechanism from balances to accounting in order to post the transaction fees to the relevant accounting ledgers

    * This is not exhaustive, and should later be applied to the other standard substrate modules. The plan for this is in V2 Totem Lego network.

* Balances module version has therefore been updated to v.2.0.0

* Removes compiling on the node-template

* Deprecates the original accounting and accounting traits files

* Updates the use of the ConversionHandler to be module specific for Bonsai, Prefunding and Orders in order to avoid cyclical inclusion issue from the accounting-pallet

* Allows for lock-mechanism to be updated to include accounting postings.

    * This has not been done yet as accounting for the lock is currently done inside the prefunding module.

This change fixes a bug where the generation of the prefunding hash was independent from the calling code. This caused issues when used with traits.

The hash is now only generated when called directly from the public api, otherwise it uses an already known hash supplied from an external module.

* Prefunding
- added tx_uid to traits
- added documentation to error events
* Orders
- propagated uid to external trait calls (prefunding)
* Bonsai
- fixed bug where the party to a record was not being checked
