Heatledger 0.9.13

This is a mandatory update, all nodes should update.
In about 18 hours from the time of this release we will reach block 65,536 which is the moment the hardfork will be applied.

This release fixes the fact where we allowed order cancellations to exist for orders that have not yet been applied. This was most likely the main cause for earlier forks. This release also contains an addition to the legacy API, added was the GetBlock call.

This release also contains the preparations needed to better keep the replication database model (what is displayed in the AE) better in sync, it uses a new event dispatching mechanism which is directly bound to the binary balance, asset and order storage components which basically ensures that if something is written to or removed from the blockchain.
It is immediately updated in the optional replication database model, this should solve the wrong display of virtual (or real-time) balances.
