Major overhaul of object→document relationship: added the Model class which models the object buffer. Each object is to be included in a model (an invariant that currently does not hold). A document is a subclass of a model. The LDObject is also now agnostic about selection, and the selection is now a set. A lot of things are probably broken now but it's a major step forward.
The LDObject::destroy method is also now gone. The model decides when objects are destroyed and calls the destructor directly. The end result removes a lot of cruft and adds structure to LDObject relations.

Notes:
- Inlining does not currently work (nothing simply gets inlined in)
- More work is required to ensure that each object actually goes into a model
