a03f06ea41 BUGFIX: Auto-claim naming scheme was context dependent. 
The automatic mechanism to assign labels to claims was dependent on the
context. In practice, a claim could get a different label when analyzed in
isolation compared to when analyzed in parallel with some other protocols. This
caused problems for the multi-protocol analysis.

1814a2d7b3 BUGFIX: Removed obsolete code that was destroying commit/agreement functionality when filtering. 
This is now (and has been for a while) handled by other code.

a7c1d8c696 Improved handling of cases with untyped variables. 
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.

ce9891d351 Disabled well-formedness temporarily. 
Simon Meier found some problems with the draft implementation, so it is disabled
for now.

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.
