6cd8007ab0 EFFICIENCY: New (default) heuristic.
Given that sk/pk/k are now hardcoded, we can exploit their occurrences with this
new heuristic.

The heuristic can now scan for the lowest term depth at which either sk or k occur.
This will cause the heuristic to favor looking for sk, then sk(x), and only later
other terms. In a small test this was twice as fast. For protocols based on pk only
the performance loss should be negligible.

The old heuristic was 162, now it is 162+512 = 674.

e42aa1215e Scyther.py: Added Caching to Scyther's Python interface.
Cached data is stored in:

Cache/XX/YYYYY.out (stdout)
Cache/XX/YYYYY.err (stderr)

Where XX^YYYYY is the sha256 hexdigest of the concatenation of the input spdl and
the arguments.

feb400c610 Added GUI error message if wxPython is not present.
If wxPython is not present, there would be a command-line message only.
Some users may not notice that. We now fall back to Tkinter to report
such messages.

e3268bb8e5 GUI: Added a large set of possible output formats to the right-click menu.
To do: We still need better error handling.
- File exists: overwrite?
- Write failed popup.
- Check for empty file at the end (what if dot does not support this particular
  output format?)

b352044f92 BUGFIX: PIL is tested at the start of the program.
Previously, one would get one void verification result before Scyther detected
PIL was not working. Now nothing is wasted.

a020cffec7 GUI: Added popup menu to save graphviz (.dot) data.
A long requested feature was the option to print graphs more nicely.
This is a solution for knowledgeable users: the dot data is more basic
and can be converted in various ways.

TODO: Simple image export.

The graph output edge remover was incorrect, and would also
remove applications that were not completely triggered by M_0 alone.

630f6e9459 Added large delta-test script.
The script runs over all protocol files it can find, and runs it using two different
command-line parameters to scyther. If the results differ, the script reports it.

The code can use some cleanup, removing e.g. global variables, but it works.

feb3827ba1 BUGFIX: Fixed crash on some include file cases.
Reported by ETH students last year: if you include a file, where the file has an
error in a line with a number higher than the original, the Python code crashes.

This is a *patch* only because the real underlying problem is that error reporting
does not take include commands into account, and does not propagate any
file names.

9605d5e772 Introduced "all attacks" switch in GUI, and a bugfix.
Passing the '--all-attacks' switch to the backend was not working. The reason
was the hack to get Vista working hardcoded cutting to the last attack found.

In the long term, this needs to be cleaned up, and cutting should be moved back
nicely to the Scyther C code where it used to work. Once done, switches.useAttackBuffer
can be set back to true.

BUGFIX: When cutting attacks/patterns, counts are no longer exact.

a0a377a84f Added switch to disable verbose exit codes.
In the near future, the default exit code behavior should be made obsolete anyway,
as the exit codes are not a nice way to report status.
It used to be convenient for shell scripting in early times,
when the parallel tests were run using the forward model
checker, but no modern script should be relying on it.

It doesn't work yet because the import fails. Weird.
