With numeric formatting gone, all output is either added direct
to a window (which will be changed soon) or done through
displayable events. Message sinks are now completely unused,
as they don't affect displayable events.

Issue #426

Instead of passing them in to the FrameContainer ctor, create
them afterwards.

This means the reference in FrameContainer can't be final but
removes the horrible setOwner() kludge that was previously in
CommandParser, and cuts down the deps needed to pass in to the
FrameContainer ctor.

From everywhere.

For now this is just a straight(ish) copy of the way Server worked.
Need to make it use events in the future which should simplify it
quite a bit.

Make these add the new window to the WindowManager, and post the
relevant event.

SM now listens to frame closing events, so Server doesn't need
to hold on to a reference and inform it that it's closing.

It doesn't really make sense in ui.core now it's doing more...
The classes it's integrating are all in messages.

Urgh.
