[Seaside-dev] WATagBrush>>class:if: with boolean and additional blocks

[Johan Brichau]

I’m very much in favour of that.

Similarly, we added a method #scriptBlock:if: to prevent generation of a script instead of only preventing its attachment. 
I don’t like the name we chose, but the concept is something I would like to push to Seaside too.
