* Add and use subxt-signer crate for WASM compatible signing * cargo fmt * dev keypairs already references * WIP fix various breakages * re-jig features to be simpler and various test fixes etc * doc and web fix * fix various bits and pieces * fix a test I broke * dev-deps can't be linked to in docs, hrmph * cargo fmt * another doc link * document the subxt_signer crate more thoroughly * move feature flag for consistency * more docs, no default subxt feature flag on signer, update release instrs * Add missing license header * unwrap_inner => into_inner * extend a test a little to better check derive junctions * note more clearly that the crypto bits come from sp_core::crypto
