805 - Update the emulation document

[ipopescu]

This PR serves as a detailed editing pass of the emulation document. Also, I found some things that are unclear and need to be checked:

• For Translating Write transforms, there seems to be a copy/paste error for ContractPackage. See the TODO.

• Why do we have protocol_version: 1.0.0 for the Version2 block? This seems incorrect in this example. See block_hash 2df9fb8909443fba928ed0536a79780cdb4557d0c05fdf762a1fd61141121422.

• The following seems incorrect. See the proposed change for this section:

  All V2 events will be omitted from legacy SSE event streams. For example, the following event will not be streamed.

  "TransactionAccepted": { "Version1": { ...

• I think we should use “Version1” and “Version2” instead of V1 and V2, to match the event content.

• If possible, I would reduce the focus on “Version1” events in the examples since this seems to be a very rare case during a network upgrade.

Merging after confirming with @zajko.
