Pasted modules should not overlap existing ones.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Build a network
2. Select the modules, press ctrl-C
3. Paste a copy of the modules with ctrl-V
4. Paste another copy with ctrl-V

What is the expected output? What do you see instead?
The second copy appears in the same location as the previously pasted copy. 
A similar issue happens occasionally when a single copy (partially) 
overlaps existing modules. Ideally, DeVIDE should paste new modules in an 
empty part of the canvas.

Options to improve the current situation:
* When pasting, find an empty area on the canvas large enough to hold the 
(bounding box of the) new modules and place the new modules there. The view 
could be moved / zoomed to show the new location if it is off-screen.
* After pasting, the new modules are selected. This makes it easier to move 
the pasted network to a new location manually.
