Sorted the methods in Model's public section.

Renamed some methods of the Model class to remove the 'emplace' word (however cromulent it is, being from STL...) from them.

Moved LDObject lifetime management from Model to ResourceVector. This is a large refactor that removes some hacks from the Model class.

Added a new type ResourceVector which manages object lifetimes, and used it to remove a bit of memory management.

Polar grid is now togglable.

CMake fixes

Added polar grid snapping code.

Added polar grid rendering (which is disabled for now).

Grid::snap now snaps points.

Simplified Grid::snap.

At long last, the grid is finally now rendered onto the viewport. Woop!

Added support for ideal co-ordinates, which should make writing editing tools a lot easier. For some reason they don't yet work with the back and right cameras.
