Introduce basic skeleton for Polkadot runtime. (#32)

* Introduce basic skeleton for Polkador runtime. * Clean up the runtime skeleton. * Make initial runtime skeleton compile. * Compile polkadot-runtime both for Wasm ad native, allowing for testing and direct usage. * More fleshing out on runtime. * Update native support. * Fix warning. * Update gitignore * Update path. * Fix path. * Remove accidentally committed files. * Add wasm binaries. * Fix test. * Native storage support API. * Add environmental module * Add native environment to make native source-code compatible with wasm. Also tests. * Finish up & polish environment stuff. * Avoid using reentrancy issues. * Add some docs and a test. * Remove unneeded function. * Documentation * Tweak docs * Remove TODOs. * Balance transfers + util methods. * Rejig tests and ensure authorities are addressed consistently. * Add marshaller for xfer function * Transaction dispatch test. * Minor fix. * Add test for ser/de transaction. * Add ser/de for header. * Add tests for header ser/de * Introduce basic block decoding/execution framework. * Introduce block decoding/execution framework (p2) * Big refactor. * Split out joiner. * Hide away support modules. * Fix up wasm runtime. * use externalities for chain_id * Clean up (Test)Externalities. * Repot and introduce keccak-256 external. * Signing with crypto. * fix unsafety hole in environmental using function * Introduce Ed25519 crypto. * Repotting. * Add ed25519_verify external. * Introduce Ed25519 verify as an external. * fix unsafety hole around unwinding * Compile fixes. * use new environmental API * Tests for ed25519 verify. * Polish * Introduce UncheckedTransaction & test. * Implement basic block and tx processing * Introduce static hex and valid signature for block test. * Repot session. * comments. * Refactor and timestamp test * Remove fluff * Remove fluff. * Staking eras and tests. * Implement sessions. * Polish * Test sessions. * Introduce better hashing. - Blake2 for secure hashing - XX for fast hashing * Fix tests. * Introduce staking. * Tests for simple staking system. * Build fix for wasm. * Fix tests. * Repotting and docs. * Docs and licence. * Documentation. * Remove superfluous code. * Remove dummy key. * Remove other superfluous file. * Optimise with swap_remove
