REAPER actions

If there’s no Helgobox instance with a Playtime matrix in the current project, this action adds one and shows the matrix. If there is one already, it shows or hides the app window. This doesn’t completely unload the app, it really just hides the window.

Works like Helgobox/Playtime: Show/hide Playtime with the following difference: If there’s no Helgobox instance with a Playtime matrix in the current project, it looks for a top-level track template called "Playtime" and adds it to the project. See Start custom Playtime from template.
