OK, this is the big one. We still keep using `#include` guards only
where we absolutely need to, but with each header now being valid in
isolation, this can now actually help *minimize* the length of each
translation unit's `#include` list. Turns out that after removing all
the duplicates, we only *actually* need to guard 29 headers across all
5 games.

Aha! TH05 actually loads every single rendered dialog image
individually before rendering it, either from the EMS area or disk.
That's one way to save memory, I guess?

Oh, an EMS function that does one single thing, and is not potentially
bugged within TH05's original sprite limits?! (Although that last part
might have just been a happy accident.)

No, I'm not copying exactly what was on ZUN's monitor during the 2010
MAG・ネット documentary. Also, this one was very lucky not to receive
a stupid function name.

64 slots reserved, 16 slots actually used, another 768 bytes of
conventional RAM wasted…
(And yes, that naming convention is indeed meant as a shoutout to all
the RPG Maker veterans out there.)
