f8a91d744d Little tweak to the key compromise modelling, model key compromise agent as a 
responder instead of an initiator, remove empty roles from key compromise
protocol.

ba47af0c42 - Test out a possible way to model key compromise: 
Add a role that sends out all messages that would occur in a legit
  run of the protocol including the session key (simulating a previously
  recorded run with its compromised session key)

- Adding a directory to play around with key compromise

b212e0b1ec - Add a dummy role in andrew-ban-concrete to work around the key symmetry 
issue (k(I,R) != k(R,I))
- Fix a typo in splice-as-cj

013afc99aa - Fixed a newly introduced bug. When the decryptor sequence unfolding 
code was added (two weeks ago), bindings were changed without changing
  the state of the graph closure buffer. This resulted in possible
  missed loops: thus, reports of broken claims could be found in the
  output, in inconsistent states. (Reported bij Gijs Hollestelle.)
  Note that this only influences the current development release, and
  not any previous results.

1bdaf7b5d9 - Large rewrite of switch code. Instead of having switch parameters in 
the (monstrously large) system structure, there is now a global
  'switchdata' structure originating in switches.c. This makes it much
  easier to see what's happening.
  * Note: although this code has been tested, there might be some
    hiccups, because doing multiple search&replace actions over all
    files is bound to cause some problems.

1331f5e7a3 - Added a global attack id, starting at one. Currently only shown in 
XML and Dot output. For Dot, it is included in the label. For XML, it
  is an added attribute of the 'attack' tag.

56c032f4a5 Update SPORE protocols to use new ticket mechanism: 
- Use builtin Ticket type instead of user type
- Remove remark that -m2 matching is required as it no longer is

4a42604cb6 - Added Ticket basic term type. Note that this only has consequences for 
the Arachne type checking. The net result is that a variable of type
  'Ticket' can always contain any term, even with -m0 or -m1 matching.

01124e2104 - Modified a number of things related to the attack analysis tools. 
* removed <term> wrappers
  * added <const> wrappers
  * removed <role><term> construct, now <rolename>R</rolename>
    constructs.
  * added <variables> section.
  * variable substitutions are followed through in runs. Thus, only
    unbound variables occur in the semitrace.
  * added the untested claims back in, so that all events in a
    role/semitrace are now shown. Note that they can be disabled
    again by using the new '-H' switch.

f22ce0dcb9 - Big change in the Arachne algorithm: decryptor sequences now get 
expanded explicitly. This solves a long-standing issue with {k}k
  decryption to yield k. Needs some testing to ensure that it did not
  introduce any new errors.

d02621c608 - Added XML term output to Scyther. This meant in fact that a lot had to 
be recoded, avoiding e.g. label="<term ..." constructs. Therefore,
  many attributes have changes into elements. Beware.
- Made bindings implicit to events using <follows> and <after>
  constructs. Also added a new <choose> for unbound simple variables.

6f6cb322dc - Fixed a protocol. The BNF of Scyther allows for non-labeled events; 
however, later this was changed, and now the tool assumes that events
  have labels. This should be explicitly checked of course.
