(svn r10114) -Fix: Only load newgrf error messages if the language matches the current
language. Since only one error can be loaded anyway, if the language didn't
match you'd get "Undefined string". Also since we're only loading one language
there's no need to use AddGRFString any more.

(svn r10097) -Feature: Add support for articulated road vehicles, or callbacks 11 and 17 for
road vehicles for those who prefer the technical explanation.

(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 r9850) -Codechange: Introduction of the Override/Substitute manager. Currently only used for newhouses.
Basically, it is more a gathering of IDs from grf files and ingame data.

(svn r9721) -Codechange: -Codechange: Cleanup of industry_cmd (Step-12). Dynamically build the legends (name and color) for industries in the smallmap_gui.
All the tiny fonts industry names should be removed from language files soon.

(svn r9560) -Codechange: add support for multiple 'base' directories for newgrf searching.
-Codechange: do not add duplicate files to the newgrf list.

(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 r9367) -Fix (r9315): If a new house doesn't have a corresponding action 3, the
graphics for the substitute (original) house should be drawn instead.

(svn r9315) -Merge: The newhouses branch. With this merge comes almost complete support for
the newhouses grf specs, so all newhouses grfs will be playable in the game.

Many thanks to everyone who contributed code and ideas, and all the testers
who found things we missed.

(svn r9037) -Feature: [NewGRF] Add support for Action 13, which allows you to translate
grf-specific texts. The translations will only be shown if you're using a
language with a grf language id and if a string hasn't already been set
specifically for the language you're using.

(svn r9031) -Codechange: Introduce grfconfig->status, and use it for states that are
mutually exclusive. At the same time, add an INITIALISED state which makes it
possible to check if a grf is not yet active but will be later on during the
GLS_ACTIVATION loading stage.

(svn r8843) -Fix

-Fix: Off-by-one error in accessing a buffer (if you start at the second byte you have to subtract one from the size)
Also avoid an unnecessary buffer copy and strlcpy() abuse
NOTE: 0.5 candidate

(svn r8838) -Feature: Show newgrf error messages loaded in Action B in the newgrf gui
window. GRFs with an error have a warning symbol shown before the name.

(svn r8831) -Feature: If an action 7/9 leads to skipping the rest of the file, disable the
newgrf if an action 8 hasn't been encountered yet.

(svn r8830) -Feature: Stop loading and disable the current newgrf if a fatal error message
in Action B is encountered. Also be more strict on the values accepted.

(svn r8825) -Fix: Make sure strings read from newgrf files are 0 terminated and 0
terminate them if they aren't, so we don't read beyond the end of the
memory allocated for the line.

(svn r8661) -Fix: [depot windows] Enlarge the blocks in the depot window if a sprite is too big to fit (ships and aircraft only)
-Codechange: depot windows default now makes a 1x1 matrix and resize the window by block size*number of blocks
This will make less vehicle type specific code and easier to read resizing based on sprite sizes

(svn r8621) -Codechange: assigned new numbers to the VEH_(type) enum so that VEH_Train is 0, VEH_Road is 1 and so on
This means that "v->type" can be used as array indexes instead of VehTypeToIndex() (or "v->type - VEH_Train/0x10 as the code still used in some places)
Surprisingly this can be done without changing the savegame format
