Build script for wpt-driver. Usage:

create-update.ps1 Release # Build in Release mode
create-update.ps1 Debug   # Build in Debug mode

REQUIREMENTS:
- msbuild.exe and python.exe (required by the Chrome compile.cmd) should be in
  the path
- powershell v.4 or more recent, with Get-FileHash cmdlet

This script has been tested in GitHub's Git Shell.
Executing it in a regular PowerShell may also work, but you will have to
setup the path for each dependencies.
