(svn r3380) -Fix: removed 'size' from r3379, because it was pretty silly
-Note: no longer showhelp publish -p, as it is deprecated

(svn r3379) -Fix: protect showhelp against any possible overflow
-Add: [ FS#15 ] Added revision / version at top of help (./openttd -h)

(svn r2962) - const correctness for all Get* functions and most Draw* functions that don't change their pointer parameters
- change a lot of byte player types to PlayerID
- beautify header files, same "#endif /* filename */" ending

(svn r2685) -Codechange: Split the music/sound/video drivers into separate files and move them into subfolders.
This results in shorter and hopefully easier to maintain files.
Note: I had to change paths in #include statements of some unrelated files, because I added the ottd base directory to the include path (-I.)
