(don't) Allow Multiple Instances

Hey,

it would be great if we had a checkbox in the config menu which would “Allow multiple Renoise instances” just like in Winamp.

Imagine that Renoise is already running in minimized mode.
You’re in your explorer and double-click on a Renoise Song because you don’t want to switch to Renoise and use its browser which would just take time.
Right now another Renoise session would start up and the song would be loaded there.
It would be nice if the song could be loaded in the already running Renoise instance.
Maybe you find some use for this idea.
