* Substantial re-work of object model. Moved many attributes out
	  of BaseEntity class. Changed WoldRouter so it now handles
	  objects in terms of Entity, rather than BaseEntity.

	* Code cleanups, including removing reduntant includes, and
	  getting rid of C style comments.

	* Fixed the way attributes are handled in Set operations and
	  when merging from an Atlas::Message::Object. This fixed
	  problem with setting gender of characters.

	* rulesets/Pedestrian.*, rulesets/Movement.*: Re-named
	  Movement variables to make them clearer. Added in
	  separate handling for collisions from moving to
	  target position. Modified collision handling so
	  objects can slide next to each other.

	* rulesets/Thing.cpp, rulesets/Character.cpp: Cleaned up and
	  rationalised movement code. Much shorter, faster and
	  more compact than before.

	* Made better use of iterators throughout, eliminating unnecessary
	  lookups, and copying of data.

	* Moved all virtual functions out of header files, making
	  less work for the linker.

	* Made more use of const references to avoid the need to copy
	  data before being able to inspect it.
