rename _Messages to Messages since it is public API
change parent class to list since Multiple Messages with same type and code may occur
deprecate lots of stuff that makes usage fuzzy (e.g. three different ways to supply arguments) and concentrate on behavior that is close to that of lists (which is what users know)
Focus
It is quite hard to figure out what the current behavior is. However, I preserved it for now and added lots of deprecation warnings.
Test Environment
