* Implement runtime version checks in `set_code` Check that the new runtime code given to `set_code` fullfills some requirements: - `spec_name` matches - `spec_version` does not decreases - `impl_version` does not decreases - Either `spec_version` and `impl_version` increase * Make tests almost work * Some fixes after master merge * Fix tests * Add missed file * Make depedency check happy? * Remove leftover `sc-executor` * AHHHHH * Reset debug stuff * Remove some 'static * More 'static * Some docs * Update `Cargo.lock`
