Update for Substrate master (#600)

* update substrate for change to palette

* change paint to palette

* update lock

* Fix missing import

* change to polkadot-master

* Use same commit hash of parity-common

* Resolve linking errors

* Rename to frame

* bump spec

* Subsume #602 and #596

* Fix DispatchInfo

* Merge `futures03` and `joe-update-to-palette` (#606)

* Change repo and branch

* Made changes

* Bumped async-std version

* Fix line width

* Bump spec_version

* Fix `run_to_block` for Crowdfund module (#603)

Probably a copy paste error.

* Bump dependencies

* Update trie-db to be inline with substrate

* Fix documentation warning

* Fix test compilation
