(svn r10961) -Codechange: Flag default substitutes of industry/tiles with a value that cannot be legal.
This avoids the forest of coal mine error in the futur

(svn r10700) -Codechange: Enable to jump (by default) to the overriding industry tile spec of the one been queried.
Only on certain very specific circumstances do we need the original spec

(svn r10570) -Codechange: Add enum required for Callback 0x22: CBID_INDUSTRY_AVAILABLE
-Documentation: Add documentation for enum IndustryConstructionType, which describes how the industry has been created

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

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

(svn r9577) -Codechange: Add notion and data for industry map colour, used in the smallmap_gui. Not used yet.
-Move the check proc array, in order to make it more useful latter.
-Add basic newGRF stuff on the industry spec. Not used yet.

(svn r9550) -Codechange: Add notion and data of industry appearing chances, both in game and in creation mode.
Not used yet.

(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 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 r7759) -Merge: makefile rewrite. This merge features:
- A proper ./configure, so everything needs to be configured only once, not for every make.
- Usage of makedepend when available. This greatly reduces the time needed for generating the dependencies.
- A generator for all project files. There is a single file with sources, which is used to generate Makefiles and the project files for MSVC.
- Proper support for OSX universal binaries.
- Object files for non-MSVC compiles are also placed in separate directories, making is faster to switch between debug and release compiles and it does not touch the directory with the source files.
- Functionality to make a bundle of all needed files for for example a nightly or distribution of a binary with all needed GRFs and language files.

Note: as this merge moves almost all files, it is recommended to make a backup of your working copy before updating your working copy.
