[FLASH-USERS] changing maxblocks

[Slavin, Jonathan]

The issue is that "just running setup again" means, I think, that you start
over with some pre-defined simulation and lose all the bits you changed.
Or maybe I'm misunderstanding how setup works.  Isn't the reason for having
MAXBLOCKS in a header file that it can be taken from there for all the
files that use it?  If not, it would be multiply defined, which would be
bad practice.
