Re: FormPreferences patch

[Angus Leeming]

I've tracked down the reason why I can't use:
        string const arg = lcolor.getLyXName(lc) + string(" black");
        LyXFunC::Dispatch(LFUN_SET_COLOR, arg);

when I'm editing the colors in FormPreferences and LyX has no document open.

About line 488 of Dispatch, there is the code:
        // We cannot use this function here
        if (getStatus(ac) & Disabled)
                goto exit_with_message;

The action is disabled without a buffer and no progress can, therefore be 
made.

I have used a work around in FormPreferences: 
        if buffer exists
                use Dispatch, 
        else
                use setColor direct.

Clearly, it would be better to allow the colors to be editted without a 
buffer present.

Anyway, I think I have cleaned up the bugs in the colors tab. Will submit 
once cvs is working again. Currently it's seems to be taking an age to do 
very little.
