Updated to download 2014 WPILib release

It seems the 2014 WPILib release is at http://first.wpi.edu/FRC/c/update/Release/ this year, and that it hasn't been uploaded to the old location at http://firstforge.wpi.edu/sf/frs/do/viewSummary/projects.wpilib/frs. They might be a few days late in uploading it there, but I changed ucpp-setup to download from the new url instead of from firstforge. The download speed is really slow, but it was the only place I could find the 2014 WPILib release.
