Cleaning up the spellchecker controller

[Angus Leeming]

I've just been looking at the code in ControlSpellchecker to see what needs 
to be done to clean up the code. I think that the first thing to do is to 
create the necessary LFUNs. Below is the existing code together with the 
proposed request that would be dispatched to the kernel.

John, I think that you know this code well. Am I on the right track?

FuncRequest(LFUN_SPELLCHECK, "end");
        bufferview()->endOfSpellCheck();


FuncRequest(LFUN_SPELLCHECK, "clearselection");
        // clear any old selection
        LyXText * text = bufferview()->getLyXText();
        bufferview()->toggleSelection(true);
        bufferview()->update(text, BufferView::SELECT);


FuncRequest(LFUN_SPELLCHECK, "selectlastword");
        bufferview()->selectLastWord();


FuncRequest(LFUN_SPELLCHECK, string("replaceword " + replacement));
        bufferview()->replaceWord(replacement);

FuncRequest(LFUN_SPELLCHECK, string("nextword " + tostr(newval_)));
        word_ = bufferview()->nextWord(newval_);

This last one is a little complex, as we would have also to pass the new 
word and modified newval_ back to the dialog through
        Dialogs::update("spellchecker", string(word_ + tostr(newval_)));
