#2 Add Flexi Connection.LinePath

[Doug]

The Bezier LinePath looks nice, but it is annoying to
have to manually set the control handles.

What if there were a LinePath type that looked like the
Bezier, but automatically adjusted the control handles
based on the layout. The (invisible) control handles
would project in the same direction as the Connector
AdjacentPoint (North, East, etc), for, say, half as long
as the distance between the ends of the connection. A
nice, smooth curve. Since the length of the control
handles are adjusted based on the total length of the
Connection, it avoids kinks.
