Update documentation on building

[dontech]

As pointed out, the current documentation is either wrong or lacking.

At least detail how to:

1. Build using Visual Studio
2. Build using command line "build.cmd"

Do you want to create a new BUILD.md file in the repo? Or we can just update the Wiki to replace the outdated info with the latest info?

Well we probably need to update the wiki anyway, or remove it.

I am kind of old-school so I was thinking of having the documentation inside the repo, so that the documentation lives with the source no matter where it is.

To keep it simple can't we just have a readme.md to put everything that was in wiki, and then update that to match current setup ?

Good idea. I think we can start with the Wiki.

I will suggestion that we keep the following three sections in the Wiki and then move the rest to README.md.
