Disable content links for SpellerPages

[MarkWB]

The user can break SpellerPages by navigating the wordWindow with links. Appending the following lines of code to the end of the writeBody() function of 'wordWindow.js' effectively disables these links:

	var find = /<a(\s[^\>]*)href=\"[^\"]*\"(.*?)\<\/a\>/gi;
	var repl = '<span style="color:blue;text-decoration:underline"$1$2</span>';
	//d.body.innerHTML = d.body.innerHTML.replace(find,repl); //memory leak for IE?
	var doc = d.body.innerHTML.replace(find,repl);
	d.body.innerHTML = doc;

(Note this suggestion is also included in the solutions I've attached to ticket #2326)
