(svn r15350) -Codechange: Create a spec array to hold the data definitions of unmovables objects.
Note that this is the very basic spec, it will be populated a bit more, later.

(svn r12157) -Codechange: Remove a structure definition and replace it with another one closely matching
-Codechange: Replace two magic numbers with according sprite names

(svn r8275) -Fix

Factor common data tables and use a bit more sensible names

(svn r8129) -Codechange: Change data tables to use split off palette map. And
include a file missed last time...

(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.
