Update Multiscreen Blank manifest

This commit adjusts the naming for Multiscreen Blank, which seems to
have dropped the v2 from it's official name. The landing page and
description for the program have also been changed. Note that this
version number may be incorrect; the website lists it as 2.3.1 but the
files reference it as 2.3.0.1.
