Bug 871, 752: Lock down enum color_mode and change option help to match.
The numbering of document.dump.color_mode and terminal._template_.colors is now the same regardless of compile-time options, unlike in previous versions. Therefore this version of ELinks may interpret a configuration file differently from previous versions even if compiled with the same options. This is unfortunate but the alternatives (keeping the numbering dependent on configuration options; defining separate options that use the new numbering; starting the numbers from 10 or so and recognizing the previous ones only for compatibility) seem even worse.
