[IAEP] Activity version compatibility

[Wade Brainerd]

This might be a good time to introduce an optional "sugar_version=..." field
into activity.info, so we can display a human readable error message when
this mistake happens.  The activity will not launch unless Sugar's version
is greater than or equal to the activity.info field.  Most activities will
not need it, but in case of using non-backwards compatible APIs it will be
handy.
Is this too big a change to patch 0.84 and 0.86 with?  It will take at least
two releases before it can have any real benefit.

Regards,
-Wade
