This change removes 32 bit support from the helper make.bat scripts
as we are dropping official 32 bit support, you can still build for
32 bit by configuring your build yourself using cmake and pointing
the LIBDIR cmake variable to your own 32 bit library folder.
There are couple of caviats currently:
- The script requires system-wide Python 3 available in the current
search PATH as python.exe.
This will get addressed soon by distributing unpacked Python binary
in our libraries.
- Since the libraries folder is to be known, this requires to have
MSVC detected. Not too bad, since formatting is still way slower
than detection, but still doesn't feel ideal.
ninja is an alternative to msbuild designed for fast rebuilds. However there is no IDE support, builds only from the command line.
Comparison between msbuild and ninja for a full build, build time in seconds.

make.bat was starting to become hard to maintain, this refactors it into separate batch files for each stage of the process.
-Improved detection of msvc2013/2015
-Improved failure handling.
-Added check for working msbuild and C++ compiler
-Added verbose switch to ease trouble shooting.
-Added Check if svn/cmake/git are in the path before using them
-Display the build configuration before asking to download the libraries
-Offer an option to recover an interrupted checkout of the libraries.
-Automatically check out sub-modules in-case they are missing.
The registry hack we were using wasn't very reliable, the recommended way to locating visual studio is using vswhere (15.2 and up), using it also allows to switch between the regular and pre-release versions.
The thing that most often still goes wrong for new users building blender on windows is checking out the libraries, some skip over the wiki, some check out to the wrong folder, in an effort to reduce the time i spend on this, I added detection of svn and misisng libs to make.bat .
When the user has svn installed, and the libdir is missing he'll be asked if he wants to download them
if svn is not installed, or the user chooses 'no' the current error message is shown.

This was set to maxcpu which in an 8 core box would be 8, each project would then spawn
8 instances of cl.exe, making a possible of 64 simultaneously running compiler instances
slowing the compile down instead of speeding it up.
Currently the tests don't run on windows for the following reasons
1) render_graph_finalize has an linking issue due missing a bunch of libraries (not sure why this is not an issue for linux)
2) This one is more interesting, in test/python/cmakelists.txt ${TEST_BLENDER_EXE_BARE} and ${TEST_BLENDER_EXE} are flat out wrong, but for some reason this doesn't matter for most tests, cause ctest will actually go out and look for the executable and fix the path for you *BUT* only for the command, if you use them in any of the parameters it'll happily pass on the wrong path.
3) on linux you can just run a .py file, windows is not as awesome and needs to be told to run it with pyton.
4) had to use the NAME/COMMAND long form of add_test otherwise $<TARGET_FILE:blender> doesn't get expanded, why? beats me.
5) missing idiff.exe for msvc2015/x64 in the libs folder.
This patch addresses 1-4 , but given I have no working Linux build environment, I'm unsure if it'll break anything there
5 has been fixed in rBL61751

- Explicitly specify the platform for msbuild, to facilitate builds with just the Visual C++ Build Tools installed.
- When vs2013 is not found, try looking for 2015 as a fallback
- Clear up any batch variables that might have been set from previous runs
- The build folder name used to be depended on the order of the parameters, this is now normalized to
"build_windows_[Release/Full/Lite/Headless/Cycles/Bpy]_[x86/x64]_vc[12/14]_[Release/Debug]" regardless of the order of the parameters.
-Use CUDA8 for all kernels when building the release convenience target with visual studio 2015
New features:
1) Release target that checks for both cuda 7.5 and 8 with WITH_CYCLES_CUDA_BINARIES=ON and CYCLES_CUDA_BINARIES_ARCH=sm_20;sm_21;sm_30;sm_35;sm_37;sm_50;sm_52;sm_60;sm_61 options set.
2) Option to switch between x86 and x64 builds, the default remains (auto detect the architecture) but can be overridden.
3) Option to switch between vs12(2013) and vs14(2015) default is 2013.
