Bugfix/windows build path spaces

[Vavassor]

This is to address #474. Since the affected batch scripts are split over submodules, I also submitted two other pull requests in Pulse-Eight/libcec-support and Pulse-Eight/platform.

I was wondering if you could do me a favor?. I am sure you have gotten to know your way around the build scripts for libcec. I think that the build scripts limit you to using VS 2012, 2013, 2015 if memory serves. There might be an issue with the C++ runtime libraries that get compiled into the installer.

I have an installer made by @opdenkamp and the dll was compiled using VS 2013 but the included runtimes were 2015. I do not know if the runtimes from the VS VC installation get used or if they are hard coded. Or to even go about fixing it if there is an issue. would you be willing to check into this and see if there is a possible issue with it?

I'm merging this PR in along with some other PRs in a few. I removed the VS version bump from this one. That'll be done separately a bit later
Thanks!
