Added a new function, CSApproxSnapshot(filename [, force=0]). This
function will take the current colors and dump them out to a new
colorscheme script stored at `filename', unless that file already exists
and `force' is not set. This may still have some bugs to work out, I'm
surprised it was this easy... Not surprisingly, it falls apart if the
colorscheme didn't set g:colors_name... And it doesn't handle
highlights the user made himself, outside of the scheme. Still, it's
a good first draft.
