completely change how we save and load containments and panels.

Browse Source 
it all happens from one file now using nested groups. this has two major effects:

 - one file to rule them all for any given corona; this makes things even nicer for use in other apps, btw.
 - the ability to easily save, send/share and restore corona configuration layouts; something i've wanted from the start
