Silent SDK Installation

[AuroraNemoia]

For the sake of installing the SDK the right way, figuring out when errors happen in specific parts ourselves and avoiding users asking if they need the Developer Toolkit for Kinect 360 as the graphical bundled installer for SDK 1.8 suggests it.

Problems to solve:

• Extracting the installers requires downloading an extra dependency, that being the WiX toolset, here https://github.com/wixtoolset/wix3/releases/download/wix3112rtm/wix311-binaries.zip
• Using dark.exe inside of the toolset to extract the MSI files from the bundled installer
• Figuring out how to install those MSIs without ruining the uninstall mechanism, which currently asks the user for the MSI file for that component, which isn't present on their system in the folder the uninstaller expects.
