Update to latest Substrate master (#320)

* Make `collator::Network` require `Send + Sync` to make it work

* Update packages

* Update to latest Substrate

* Make it compile and make tests work

* Use `polkadot-master`

* Fix CI

* Remove `build.sh` from readmes

* Delete old stuff

* Bring one back
