* WIP Implementing new event subscription API * back to lifetimes, fix example * no more need for accept_weak_inclusion * thread lifetime through to prevent 'temporary dropped' issue * make working with events a little nicer * Get tests compiling * fmt and clippy * _name back to name * dont take ownership, just have stronger note * Attempt to fix test * remove commented-out code * Add a couple more helper methods and a test * Remove custom ExtrinsicFailed handling; treat them like other events * Handle runtime errors in TransactionProgress related bits * cargo fmt + clippy * Fix some of the failing tests * remove unused import * fix transfer_error test * Fix compile errors against new substrate latest * Comment tweaks, and force test-runtime rebuild * Drop the TransactionProgress subscription when we hit 'end' statuses * cargo fmt * find_event to find_first_event and helper to return all matching events * TransactionProgressStatus to TransactionStatus * Copy and improve docs on TransactionStatus from substrate * debug impl for Client to avoid manual debug impls elsewhere * Add and tweak comments, specifically a note about block inclusion on errors * clippy + fmt * Fix docs * Ignore 'error' statuses and adhere to the substrate docs * tweak and improve some comments per @dvdplm's suggestions * Break transaction* structs into separate file * fmt and fix doc link
