(svn r1503) Added feature:
o allows users to setup the production values of the rawmaterial producing
industries in the editor

Modified:
o ttd.h - added CT_INVALID for 0xFF cargo type
o english.txt - added 1 string
o industry_gui.c - the feature itself
o window.h - added compile asserts to the structs which checks whether their
sizes are smaller than WINDOW_CUSTOM_SIZE

Thanks:
o Darkvater to bother me to constantly improve the patch
o Various users at #openttd for testing

#include <stdio.h>

// This pretty simple file checks if the system is LITTLE_ENDIAN or BIG_ENDIAN
//  it does that by putting a 1 and a 0 in an array, and read it out as one
//  number. If it is 1, it is LITTLE_ENDIAN, if it is 256, it is BIG_ENDIAN
//
// After that it outputs the contents of an include files (endian.h)
//  that says or TTD_LITTLE_ENDIAN, or TTD_BIG_ENDIAN. Makefile takes
//  care of the real writing to the file.
