[Glass] [ANN] GsUpgrader

[Dale Henrichs via Glass]

Good catch ... I think:)

You are right, GsUpgrader shouldn't be hitting conflicts for Grease...

My inclination is to fix this and "force" the github-base Grease to be
loaded (unless the Grease project is locked, in which case the lock wins),
since the bugfixes there will always be more current ...

What do you think?
