* Copy-Pasta owner and freezing code from `message-lane` * Halt pallet if bridge hasn't been initialized * Make owner optional in `message-lane` pallet * Add `is_halted` to `InitializationData` * Fix initialization tests * Only allow pallet to be initialized once * Add some logging around halting and ownership changes * Remove `target` in debugging calls
