Connection in graphical should draw crossings properly

[kbirken]

If two connections in the graphical editor cross each other, it is not possible to distinguish which goes where. Little "bridges" should be drawn instead of plain crossings. Or dots should be draw if the crossing is actually a merging of connections. See attached example from current implementation (which contains both types of crossings).
