jp: added jp/debug commands: jp/debug hierarchy contain commands useful for developping and debugging. first commands are jp/debug/bridge: - "method" allows to call a bridge method, args are parsed as python arguments (using eval). - "signal" do the same to send a signal from backend, using the new debug plugin.
