Suggestion: Add a generic sidechain and further missing essentials structures #90

Hi,

currently the representation of the following common song's structures still are missing:

• A simple sidechain structure (I think a "receiver"-approach instead a classical sender-view would be beneficial here, so the target holds the sidechain information, not the sending device, please also read here: Suggestion: switching to "receiver" approach, getting rid of the send device #91 )
• A simple group container (the group track structure maybe could be reused, marking tracks as type="inline" or something)
• An util device being able to capture a gainer, a panner, phase switching and L/R switching
• Loop region

So I would like to suggest to you to implement these ones, too. I might have overlooked other missing essentials.

Dawproject is really great, it so useful to be able to switch daws while working on a project! It is time to think this project bigger, in my opinion.
