Max and Min version is something that would be nice to have in the 
plugin header. Min version being required, Max being optional, because 
we see what happens in Firefox when somebody sets the max version at 1.5 
and comes out and half of your extensions you just got to work 
with 1.5 are disabled again. Doh!
