Make substrate generic (#169)

* Some initial work on RPC and client

* Rephrase as params

* More work on traitifying substrate.

* Traitify in_mem.rs

* traitify client.rs

* Make new primitives (mainly traits) build again.

* Many (superficial) build fixes throughout.

* Fix remaining build issues up to bft interface.

* Make bft primitives be generic.

* Switch out MisBehaviorReport for generic version.

* Merge Hashing into Header.

* Update runtime for new generics (with Hashing).

* Update demo runtime.

* Make runtime compile.

* Build fixes for runtime

* Remove old modules.

* port substrate-bft to use generic substrate types

* port client

* port substrate-test-runtime

* mostly port test-runtime to get compiling for std

* Ensure `AccountId` has a `Default`.

* Fix type deps.

* finish porting

* initialize test_runtime from genesis correctly

* remove commented code

* maybe unsigned signatures

* runtimes compile

* port over most of network

* serialization for generic types

* fix comment

* remove some unnecessary trait bounds

* network compiles

* tests compile for sync

* fix deserialization

* temporarily remove deserialize derives

* workarounds for serde issues for deriving deserialization

* get demo-runtime compiling on std

* port extrinsic-pool

* primitives reshuffling

* get network compiling again

* remove debugging file

* runtime tests now passing

* port client-db

* start to port over substrate-rpc

* mostly port over PolkadotApi

* test_runtime follows normal conventions

* substrate runtime tests pass

* deal with inherent extrinsics correctly in polkadot-api

* port transaction-pool

* port polkadot-consensus

* port substrate-rpc

* everything compiles

* tests compile

* fix grumbles

* test-runtime uses its own transfer type

* switch to master branch of jsonrpc

* fix network tests and some warnings

* all tests pass locally

* [ci-skip] add another comment about issue

* remove some curlies
