Failures in lates one_mode branch

[JNmpi]

I really like the new double click feature. It makes the gui much more intuitive. However, I realized two bugs:

• When selecting and deselecting a node I cannot select it again. I first have to select another node. This is rather unintuitiv.

• When selecting the ForEach node and double clicking on the canvas nothing happens. I guess the color definition is missing. At least this is the error I get when I try to load my example workflow.

@JNmpi, unfortunately I can't duplicate this on my machine. I agree the described behaviour is bad, but we might need to look at it next time we're on Zoom together so we can track down where it comes from.

Yep, your guess was spot-on. Fixed in #19.

Nevermind, I can get this to happen. It occurs only when clicking on the body of the already selected node. IMO this shouldn't even be deselecting it -- it violates the spec draft in CanvasObject.__doc__. Shouldn't be hard to fix.

Fixed in #20 now.
