5c2eded8f9 Weakagree and Alive claims now also allow for a role parameter + BUGFIX. 
Previously, weak agreement and aliveness claims would enforce a requirement for all agents in the range
of the rho of the claim run.

For some three-party protocols this was stronger than needed. We now allow an
optional role name parameter for these claims; if such a parameter is used, the claim
is only evaluated for the agents performing that role.

En passant fixed a potential bug: aliveness and weak agreement require a run for each
agent, but previously we didn't check if these were helper protocols. Clearly they
should not be.

fedd729ab2 Added support for inequality tests. 
There is a new event:

  not match(t1,t2)

where t1,t2 are terms.

They are implemented by using a special claim that simply stores the
intended inequality. The pruning theorems (prune_theorems.c) ensure that
these terms never become equal. If there are equal, the constraint is
violated. As long as they are not equal, there exists a solution using
groung terms such that their instantiation is not equal.

Currently not very efficient implemented and the graph out output is
also ugly for now.

f883499d07 CHANGE: Changed setup of running & commit. 
Now:

claim(A,Commit,B,data) => claim(B,Running,A,data) and also B is running the right protocol and role.

66e18deb3f NEW: Added claims: Commit and Running. 
There are two new claims:

  claim(X,Commit,t)  : check for agreement on data
  claim(X,Running,t) : signaling claim

The property checked is that each claim Commit needs to be preceded by a Running
with an identical term t.

Cherry-picked from commit 99a6be00e9d3d219ec73665607e8a3a7d65d04d1

- If labels start with a bang (!), they are ignored in synch/agree
  claims.

5487d3ae90 - From this version onwards, Scyther no longer supports the modelchecker 
method. A big cleanup has been started, but is not finished yet, so
  minor artefacts might still remain. These are to be cleaned up later.
