Changed implementation of logging macros.
...
We have observed some strange performance-related behavior as described here: https://stackoverflow.com/questions/29652787/adding-stringstream-cout-hurts-performance-even-when-the-code-is-never-called
This set of changes addresses this problem. The old macros would simply expand the logging code in place, whereas we now have logging functions and the macros call these. Overall I believe it is tidier.

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.
