Mondrian should provide teh start and end nodes in the edge action

[seandenigris]

Originally reported on Google Code with ID 396

Right now, an edge action block takes as parameter only the model of the edge.

The model of the edge is mainly targeted to identifying the start and end node, but
it many times is 
not enough to do something with the edge afterwards.

By providing the start and end node in the action block, we take advantage of the already
computed 
nodes.

To not break existing code, an idea would be to use something similar to glamourValue
through 
which the block parameters are optional.

I started to work on this (testHandlerOnEdge). However, I am unsure for few things.

view interaction on: MOMouseDown do: [ :v | ... ]

What v is supposed to be? The announcement or the value on which one has clicked? 
It has to be the value I believe. However, it may brake already existing code. We could
leave it like this, and introduce on:withValueDo: 

What do you think?

Cheers,
Alexandre

In Roassal, the block in on:do: receives an event, that contains the model. Much cleaner
than in Mondrian!
