Fix: missing filled flags in various levels

This is an omission in the filled/prefilled unification. The default for
filled on regions now being 0 meant that regions that had previously had
no need for any fill declaration at all (regions' prefilled defaulted to
0 before this, the effect being to fill them) now failed to get filled.

The rule of thumb is that all des.regions with a type for which filled
is meaningful (e.g. special rooms) should declare the fill status. I
added it to a bunch of temples even though this doesn't really seem to
affect anything there (the priest and altar come with the altar
definition). I assigned temples filled=1 and filled=2 loosely based on
if there is ever being some other generation that would put other
furniture or items in a temple, but the distinction should not affect
anything right now.

Cases fixed where non-temple regions weren't getting filled:
- Barracks, a graveyard, and shops in Tou-goal
- The beehive in the Wizard's Tower
