Reload the pd_lua script

[yueduz]

When modifying a pd_lua script using the internal window, the script can be automatically reloaded after saving. But when modifying a script using an external editor, how can it be reloaded?

I don't think there's a way to do this with a message currently. I'll add this later!

Just a manual refresh button can provide great convenience
