* rulesets/mason/world/tasks/Combat.py: Re-work the way combat works so all involved entities do their own tick ops, rather than the whole thing being coordinated by only one entity. This simplifies removing the task once obsolete. * rulesets/Py_Thing.cpp: Add get_task() on Character so task is available to scripts. * rulesets/Py_Oplist.cpp: Allow an oplist to be appended to an oplist as well as being added. * rulesets/Character.h: Add an accessor for task. * rulesets/Character.cpp: Ensure a task is cleared if it does not get initialised.
