* Run RustFmt as part of the CI

* Format repo

* Run RustFmt before the default Travis build step

Apparently if you override `script` you also need to make
sure to `build` and `test` the code yourself.

* Format repo

* Update dependencies

Upgrades Substrate based dependencies from v2.0.0 -> v2.0.0-alpha.1
and uses the `jsonrpsee`'s new feature flags. The actual code hasn't
been updated though, so this won't compile.

* Use `RawClient`s from `jsonrpsee`

* Update to use jsonrpsee's new API

* Hook up Ethereum Bridge Runtime, Relay, and Node Runtime

* Bump `parity-crypto` from v0.4 to v0.6

Fixes error when trying to compile tests. This was caused by
`parity-crypto` v0.4's use of `parity-secp256k1` over `secp256k1'.
Using the Parity fork meant multiple version of the same underlying
C library were being pulled in. `parity-crypto` v0.6 moved away from
this, only relying on `secp256k1` thus fixing the issue.

* Bump jsonrpsee from `de7cbf2` to `a0bea41`

Bumps [jsonrpsee](https://github.com/paritytech/jsonrpsee) from `de7cbf2` to `a0bea41`.
