RootDirectory, EngineDirectory, UnrealBuildToolPath are now found in BuildUtilities' UnrealBuild namesapce.
The way these are computed has changed. Previously, it was assumed that the application is UnrealBuildTool, and paths were constructed relative to that assembly.
Now, the assumption is that the process is located under a "Engine/Build/DotNET" sub-path and paths are constructed relative to that.

Also fixed so that HololensTarget is actually getting configured from setting sources, including command line and BuildConfiguration.xml which I added attributes for to match how Windows targets can be configured.
