* [core] Add `ext_deposit_event` runtime call bindings

A litle bit of guessing how to integrate this into PDSL using the [commit for adding println](https://github.com/Robbepop/pdsl/commit/8517e0b9a97132e714cb9d894bab35daa9385e33) and [commit for ext_deposit_event](https://github.com/paritytech/substrate/commit/e748c33c8ef40bd51dc122b7f11fcf26b8354957)

Right now, I have it so test_env prints the event data when it is called. Is this right?

Is anything here right?

* [core] Fix printing of vec for `deposit_event`

* [core] Run cargo fmt

* [core] Fix comment and Vec<u8> to &[u8]

* [core] Add `events` storage in `test_env`

This is pretty hacky until we have a more defined plan around types from `node-template`

* [core] Fix mutability across events

* [core] Fix comment

* [core] Use `EventData` rather than `Vec<u8>`

* [core] Add derive traits to event data

* [core,model] Rename & add model api for `deposit_raw_event`

* [core] Fix compilation issues and fmt

* [core] Update function name to `deposit_raw_event`

* [core] Fix cargo fmt

Adding the ability for contracts to get the random seed of the block.

Returning the value as a Vec<u8>, although within substrate it is treated as a `Hash`... should/how do I use the `Hash` type?
