Industries: support 16 cargos in / 16 cargos out #15
I made another PR to this PR branch, removing some deprecated industry properties: PeterN#3
Apart from taking out the deprecated parts, this needs some better error reporting (if possible) of the old syntax, a migration guide, possibly better examples, and also support for 16 accepts for town houses.
FIRS branch that compiles with this and works as expected: https://github.com/andythenorth/firs/commits/v4-development-track
There are no nml docs currently. Best reference is nml examples, and https://0x0.st/zHBc.txt
Newgrf wiki is up to date for the nfo spec on these changes.
I favour shipping this sooner not later, nobody else is likely to test it. Best to get it in the hands of authors and fix any bugs that come up.
