COE Model Report Task: Rich Text Editor, "Only Web-Safe Fonts" Option
Bug Number: n/a
Release notes (y/n): Yes
For Release Nums: 6.7

See the new checkbox: [x] Only Web-Safe Fonts:
http://cadswes2.colorado.edu/~philw/2015/CoeModelRep/2015-04-26/OnlyWebSafeFontsOption.png

This option is currently enabled (exposed) with this symbol in 
RwDoc/RichTextEdtior.cpp:
static const bool SHOW_WEB_FONTS_OPTION (true);

See google results on "web safe fonts", including this webpage:
http://www.w3schools.com/cssref/css_websafe_fonts.asp

Note: Expanding these fonts within the generated inlined CSS font-face 
styles to a sequence of fallback fonts was implemented, but was disabled 
(based on the following symbol).  Multiple fonts in these styles ARE NOT 
round tripping well through the QTextEdit widget.  That is putting single 
quotes around the whole list, rather than individual fonts -- and that 
BREAKS the CSS. The font specification no longer works, and the browser 
is defaulting to something else.
static const bool ENA_EXPAND_WEB_FONTS (false);

The supported Web Safe Fonts are defined in the following method.  
(The fallback fonts do play in a limited way, but are ultimately not 
provided in the generated HTML/CSS -- see the note above):

// static, private
void WebFontUtils::buildFontGroups()
{
   // build only once
   const int cnt = WebFontUtils::FontGroup::_groups.count();
   if (cnt > 0)
      return; //----->>
