Markus Armbruster 43a0a4a451 update: Reorder feeding, tax & plague for consistency
People in sectors get plagued, then taxed or paid, then fed.  People
on ships and land units get paid, then fed, then plagued.  Sectors
were messed up when Empire 3 made the update code work for budget.

Change sectors back to how they worked before Empire 3: move do_feed()
from produce_sect() to prepare_sects(), and delay do_plague() until
after do_feed().  People in sectors now get taxed, paid and fed even
when they die of the plague, just like they do on ships and land
units.

Because do_plague() now runs after populace(), the latter's handling
of people dying off doesn't cover plague anymore.  Delay it to the
very end of prepare_sects().

Additionally, move feeding and plaguing from upd_ship(), upd_land() to
prep_ship(), prep_land(), for consistency with sectors.

This document gives a rough order of events during the update.
.s1
.nf
1) Prepare
a) prepare all ships
a) pay military on board
b) feed people on board
c) plague people on board
b) prepare all planes
a) pay crew
c) prepare all land units
a) pay military on board
b) feed people on board
c) plague people on board
d) prepare all sectors
a) fallout is checked, if FALLOUT is defined
b) guerrilla warfare is checked
c) if there are no civs or mil in the sector, it
reverts to the deity
d) taxes are collected from civs & uws; mil are paid.
e) if the sector is a bank it makes $$ proportional to
its efficiency
f) people in non-sanctuary sectors eat
If not enough is available, the excess people will
starve off. No more than 50% of the people
in a sector can die; the uw's die first, then
the civs, then the mil.
g) if there was starvation, the work percentage is set
to 0, otherwise the work rate rises by
8+(1-15), max of 100
h) population grows and is truncated
i) if the sector doesn't have the plague, see if it
catches it
otherwise plague the people
e) pay for military reserves.
2) Produce
a) ship maintenance, in order of ship number
b) plane maintenance, in order of plane number
c) land unit maintenance, in order of land unit number
d) sectors, top to bottom, left to right
a) pay sector maintenance
b) sectors that are stopped are skipped (see info stop)
c) first increase eff
d) then make things
e) ship building, in order of ship number
first increase efficiency, then produce
stopped ships are started, but not built (see info stop)
f) plane building, in order of plane number
stopped planes are started, but not built (see info stop)
g) land unit building, in order of land unit number
stopped land units are started, but not built (see info stop)
3) Then, do deliveries for all sectors in the world, row by row, going from
top to bottom, left to right
4) Then, do exporting via distribution for all sectors in the world, row by
row, going from top to bottom, left to right
5) Then, do importing via distribution for all sectors in the world, row by
row, going from top to bottom, left to right
Also start sectors that are stopped
6) modify tech/res/hap/edu levels & do tech bleed
7) decrease levels due to passing of time
8) update war declarations (for slow war)
9) If MOB_ACCESS is not enabled, mobility is updated as follows:
a) Add mobility to ships
b) Add mobility to sectors
c) Add mobility to planes
d) Add mobility to land units
