Fixed up some broken logic around detecting
loadedProfiles as the currentProfile. Now when
we load the profiles from disk we also correctly
check whether one of the profiles is in use now
and if it is then we use that profile instead of
creating a new one.
Was missing a SetTopologies command from upstream
and the latest GeForce devices don't seem to be able to
read EDID which means the Topologies dont have a
DisplayName peroperty, which in turn causes issues when
trying to change to that topology! So now detect empty
DisplayName and fill it with a default.
