Replaced uses of LDSpawn with the Model class in edit modes

Removed dead code that's standing in the way of refactoring

Removed the AddObjectDialog. Garbage code that absolutely needs to be reimplemented.

Made the quad→triangles use emplacement. However, now it crashes because of problems in the underlying system (the LDObject constructor shouldn't do anything in regard to the model!)

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.

Happy new year 2017!

Matrices are now input with 9 spinboxes instead of a MLCad-style line edit
