(svn r10347) -Fix [FS#948]: industries with a very low production could never recover when using smooth economy.
-Fix: in smooth economy producing industries could not close, whereas they could close in non-smooth economy.
-Fix: in smooth economy the "do not increase production" flag of industries was ignored.

(svn r10232) -Fix(r1): _numof_industry_table never was composed of 12 entries. Only 11.
It never hurt before, but it would have...

(svn r10226) -Codechange: Add support for newindustry tiles drawing.
Heavily based on Maedhros's newhouses implementation

(svn r10099) -Fix(r9867, FS860): Use the specs of the to-be-created industry instead of the scanned industry
Spotted by Oxygene

(svn r10063) -Codechange: Change VARDEF for extern
-CodeChange: Add the count of industries, basic support for variable 67, var action02 forindustries

(svn r9992) -Codechange: Remove some hardcoded references to Industry IDs.
A few more to go

(svn r9976) -Codechange: Declare a writable array of specs for industry and industry tiles.
It will be initialized by the original data upon game start.
Rename some enums to be more consistent too

(svn r9762) -Feature: Two new difficulty settings : Very low number of towns and very low number of industries
Based on FS#289, by pitt2

(svn r9705) -Codechange: Merge some data arrays together, making a bit more logical units.
Calculate with a macro (for _industry_anim_offs_toys) the value of x, instead of doing it at run time.
And give some more descriptive names too...

(svn r9676) -Codechange: introduce NUM_INDUSTRYTYPES instead of IT_END.
This makes the code clearer.

(svn r9371) -Feature: Add support for variable snow lines in the arctic climate, supplied
by newgrf files. When this is enabled forests cannot be built below the highest
snow line, and farms can't be built above it. Houses still use the
_opt.snow_line so they are all consistent, so to make them respect the snowline
you may want to use some newhouses features as well.

(svn r9162) -Codechange: Cleanup of industry_cmd (Step-8). Gather tile animation data into IndustryTileSpec array
Added a few documentation on remaining animation arrays (mostly ToyLand ones)

(svn r9097) -Fix [FS#525]: open and close messages now have their own setting, so you can hide economy changes, but do show open/close of industries
-Change: store news_display_opt in his own section, so it is no longer stored as uint in openttd.cfg (allows adding news-types easier)

(svn r8827) -Codechange: Cleanup of industry_cmd (Step-6). Implementation of IndustryTileSPec, the alter ego of IndustrySpec.
It offers identification of the different industry tiles in a more distinct manner, as well as regrouping scattered pieces of data across the sources. More to come

(svn r8535) -Feature: Allow lumbermill to cut trees only when they are full grown.
This does not affect output of the mill, but make the visual aspect of it more accurate.
Prior of this, the mill produced cargo of the same amount even if the trees are on their first stages of growth.

(svn r8485) -Fix

-Fix (since the dawn of time): Remove phantom oil rigs sometimes present in old savegames

(svn r8128) -Codechange: Split sprite and palette remap into separate 32 bit values.
This lets us increase the sprite width from 14 to up to 29 bits,
effectively nulling the old sprite limit. Table changes in next commit.
