* common/Property.cpp: Add some specialisations that are useful
to cover in the tests, even though we are not using them in
the server yet.
* common/inheritance.h: Provide an accessor for the dictionary of
class objects for testing purposes.
* rulesets/AreaProperty.cpp: Use Map() rather than isMap() once we
have already tested it.
* rulesets/Entity.cpp: Remove some debug output.
* server/CorePropertyManager.cpp: Remove some debug output.
* tests/PropertyExerciser.h, tests/PropertyExerciser.cpp: Fill out
the functionality of the property tester. Add functions to get
random values. Use vector for value storage to make it easier
to generate the random values.
* tests/AllPropertytest.cpp: Cover all the property classes we can
test.
* tests/Makefile.am: Add mercator libraries to the property test,
as we are now testing the terrain property.
* tests/PropertyExerciser.h, tests/PropertyExerciser.cpp:
New class which thoroughly exercises any property class via its
base interface.
* tests/AllPropertytest.cpp: Start passing all property classes
through the as yet incomplete exerciser.
