Bumped SourceCodePro to 1.017

 - Totally overhauled font install process since the previous version
 required lots of interaction / prompting to upgrade existing fonts
 AND had a clunky UI dialog when installing fonts for the first time
 - Leveraging Windows Powershell sample script that compiles C# on
 the fly to call Win32 APIs that deal with fonts
 - Elevate to admin to run the new stuff - no reboot required
