6374683d17 Visualisation improvement: role variables get priority in assigning concrete values. 
Previously, if a local (non-role) variable would have (implicit) agent type,
it would be assigned a concrete term before the roles. This would lead to
non-optimal choices, since we care more about the role instantiations than about other variables.

However, when making traces concrete, we use the run's 'locals' list. Because of
the way this is constructed (in reverse), non-role variables precede the role variables.
We therefore choose to traverse the list in reverse.

b0e5128e23 Attack output improvement: better choice of agent names. 
When an attack pattern is displayed, Scyther instantiates open variables with concrete names.
This is often more intuitive for humans.

In the case of instantiating role names, we often ended up assigning Alice to the B role and
Bob to the A role. This patch provides a more clever heuristic to find agent names
that start with the same letter as the role (variable) name. In case this fails, we
still try to map Alice to roles starting with 'I' and Bob to 'R', and otherwise we just pick something.

Also added "Simon" and "Pete" to cover some common role names.

45d5cb0a3a Cleanup: Cleanup of some spacing, conform coding conventions. 
This is simply the result from running reindent.sh again.

7658644295 Rati Gelashvili reported a rare but annoying bug in the hash function handling. 
The fix requires a significant reworking of the function handling. This
is a first attempt.

Conflicts:
	src/knowledge.c
	src/knowledge.h

Regression test suggests that the Hashfunction fix works.

a93b555b1a Added cast to solve long-standing compilation warning. 
Note that the cast does not seem to be needed after manual inspection, but

This includes a number of single patches, ranging from the vista fix with the buffers, to the start of many new minor features.

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.

b16023bf0e - Cleaned up heuristic code. Note that there is a "hidden" heuristic: 
implicitly, older goals are resolved first, if some goals have equal
  weights. This is encoded in the "w <=" comparison; if this is set to
  "w <", the heuristic becomes much less effective.
