Split Indices module from Balances (#1404)

* Indices module

* Remove indices stuff from balances

* Rejob node, move Lookup into system.

* Fix up some modules.

* Fix democracy tests

* Fix staking tests

* Fix more tests

* Final test fixes

* Bump runtime versions

* Assets uses compact dispatchers

* Contracts module uses indexed addressing

* Democracy has more compact encoding

* Example now demonstrates compact eencoding

* Sudo uses indexed address

* Upgrade key also uses indexed lookups

* Assets more compact types.

* Fix test

* Rebuild runtime, whitespace

* Remove TOODs

* Remove TODOs

* Add a couple of tests back to balances.

* Update lib.rs

* Update lib.rs
