Applied default Visual Studio formatting to most files. This is a quick fix for the tabs vs spaces issue that messes up the formatting in any editor (esp. Linux) which handles tabs/spaces differently to Visual Studio. Some parts of the formatting look a bit worse but overall it should be better (or at least more consistent).
...
I didn't apply the changes to a few macro-heavy files as Visual Studio removes all indentation from macros, whereas the indentation can be handy to see nesting.

This commit knocks about 30% off the run time of the sampler tests by using a more efficient check for whether we are near the edge of the chunk.

Commented out optimized path in sampler as it doesn't work now that we are using Morton ordering for the data in chunks. However, we can probably reinstate such a fast path if we give some thought as to how it should be done.

Replaced Vector3D with integer as key to map.
...
Chunks of voxel data are stored in a map, and it is quite common to need to search the map for a particular chunk. The key type used to be a Vector3D (i.e. the position of the chunk in 3D space) which makes conceptual sense but is relatively slow. Using a Vector3D as a key seems to have overhead, probably in terms of copying and performing comparisons. It seems to be significantly faster to use an integer as a key, so we now take the 3D position and pack it into a single integer by bitshifting.
Naturally this reduces the range of positions we can store - a 32-bit int can only encode 3 x 10-bit values, which means our volume can only be 1024 chunks in each direction (with a chunk often being 32x32x32 voxels). This should still be large enough for most uses, but an upcoming change will allow 64-bit keys to be used (at least on 64-bit builds) which then allows 21 bits of precision per component. This is so large that it's almost infinite for any practical purposes.
