Traitify Runtime (#104)

* Factor out safe-mix and dispatch

* Refactor dispatch into something more modular.

* Fix wasm build.

* Fix up timestamp

* fix warnings.

* Borked timestamp example

* Fix build

* Timestamp as skeleton for traity runtime.

* New storage macro.

* Dispatch module has traity API.

* Move consensus module to new API

* Refactoring and outer dispatch

* Avoid unnecessary derives.

* Abstract the low-level half of system.

* nicer outer dispatch syntax.

* Make runtime compile again (albeit in a heavily simplified state)

* Reworking runtime and the upper levels of system.

* Initial reworking of runtime:

- Introduced executive module;
- Introduced trait primitives module;
- Provided an API endpoint.

* Expose an additional function in system

* Another couple of functions traitified in executive.

* another function in executive traitified.

* One more function traitified.

* Finish traitifying executive!

* Traitify session module.

* Cleanups and ensure session gets run.

* First part of traitification of staking module.

* Bit more of staking traitified.

* Additional stuff in staking. Fix up session.

* Penultimate part of staking module.

* Final part of staking (code)

* Update demo runtime to include staking.

* Final tweaks for staking integration.

* Remove old runtime files.

* Schedule staking.

* Minor fixes

* First bits of democracy.

* Democracy module integrated.

* Fix warning.

* Traitify and integrate council module

* Council voting.

* Runtime binary and tweaks.

* Binary update.

* Fix `*Type` grumble.

* Fix up genesis_map

* Remove NonTrivialSlicable

* Staking "test externalities" stuff along with refactor.

* Add session test externalities constructor

* Fixed executor tests.

* Make one test in executive module work.

* Remove test framework stuff into common module.

* Enable other tests in executive

* Session tests reinstated, minor refactoring of keyring.

* Fix staking tests.

* Fix up democracy tests.

* First few tests in council.

* Council tests reinstated :)

* Avoid hardcoding blake2 into Header.

* Fix last few tests.

* Make all primitives generic.

* Fix tests.

* Refactor runtime to remove genesismap.

* Streamline runtime more with macrofied config.

* Clean paths

* Fix warning.

* Consolidate demo runtime crate.

* Remove stale code.

* Refactor away dodgy trait.

* Add corresponding Aux type.

* Fixes
