When untyped variables occur, the encryption level depth pruning is for
now unjustified. Maybe we can get a proof later. Previously this was
hidden, which was a bad design decision. Now the output is much
clearer.
This cleans up some graphs rather nicely. There is only one potential
drawback (not observed in practive):
If two bindings have the same from/to, but different interpretations,
we might lose information. In particular the 'select' intermediate nodes might
pose a problem and we would be better off by not having any interpretation on
what is selected.
This switch was previously known as '--state-space', but the new name is
much better.
Backwards compatibility:
'-c' was previously used by '--check', so check is now abbreviated to
'-C'.
'-s,--state-space' still works but is from now on considered to be
deprecated.
Currently, both my Feisty Ubuntu's have stopped working with the GUI of
Scyther. So to be on the safe side, PIL is disabled for now, until I've
resolved the problem.
The error is the following:

Great. Bounding boxes in eps again.
I've added a marked for the Athena problem case, and now no more false 'complete proof' results are produced.
However, the tool reports, 'no attack within bounds', which is slightly inaccurate
depending on the interpretatio of 'bounds'.
Since a while, wxPython has been refusing to correctly display strings with a dash in them in the staticText object. Given a string "xx-yy", only "xx" is displayed. This caused some problems for protocols with dashes in their protocol names. I've worked around it by replacing all occurrences of "-" by "_".
The old version numbers were retrieved from SVN; of course this no longer works. Now no versions are retrieved on normal building. Instead, this is covered by the dist building script.
