I think there is no equivalent in 0.8 at the present. The 0.7.2 game
variables was a hack for supporting tutorial messages.

We should implement a system for scripting that can be used by
maps/scenarios/campaigns. With such a system, tutorial messages should
rather be displayed by invoking some sort of trigger associated with a
display-message action. A scripting environment should include support for
setting and getting variables.

Great, we should maintain support for 0.7.x maps at least until the 0.9
release.

No, people can complete their games in the old version before upgrading
(although we should maintain backwards compatibility for bugfix releases).
