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.
