Replace echo -e with printf in scripts

Fix albinism override not being set correctly

Closes #1358

See merge request pregmodfan/fc-pregmod!5925

echo -e is not POSIX compliant, and as we have to use #!/bin/sh shebang
line, echo might very well be unaware of "-e" argument. Therefore we
replace it with printf.

Bugfix

Account correctly for sex supply barriers and subsidies

See merge request pregmodfan/fc-pregmod!5922

Fix increaseWetness()

See merge request pregmodfan/fc-pregmod!5923

OK, that's a lot more broken than I thought...rip all the subsidy/barrier accounting and push it all into a common function that actually works correctly and tells the player what it's doing.
