Fix check logic for SetupMode variable.

After going back and inspecting this further, the logic for "SetupMode"
being present at all was incorrect.  Also initialize our state earlier
so it's sure to always be set.

Bump version to 0.7.

Do not use 0.6; on some machines it misunderstands the SetupMode
variable.
