(svn r8969) -Codechange: rework of the player face bits.
- introduce a new format (with backward compatability) that is more clear and needs a much simpler face drawer
- replace tons of ifs/switches/magic numbers by table lookups

(svn r8300) -Codechange: Add a prototype for DrawPlayerIcon to players.h and include that
instead of using externs. Also move DrawPlayerIcon from graph_gui.cpp to
players.cpp.

(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.
