Introduce two convenient sprite iteration macros in build.h, add a few uses.

Browse source 
Defines SPRITES_OF(Statnum, Iter) and SPRITES_OF_SECT(Sectnum, Iter)
[The first is so that STAT_* can be substituted for Iter and it reads nicely.]

Usage should be self-explanatory, but one thing to keep in mind is that
the sprites that are iterated over MUST NOT be deleted.
