Well, given the current state of the code, it's hard to plan changes to 
give activity authors a few days to update their code. This particular 
change happened because of some refactoring I needed to be able to keep 
working on the journal UI.

I think this kind of breakage (etoys not starting) in the daily builds 
is acceptable. I'm doing what I can to avoid but I don't want to slow 
down development because of it. Sugar is in alpha state, it's not yet 
the time to pretend fully stable builds everyday.

Clearly if there will be major changes, this will be done more 
carefully. But this was only a one liner, trivial change.
