[Chameleon] Nautical Miles units

[Jan Jansen]

Hi Jesse,

here's the code (http://www.skullsite.com/download/rulerNM.zip), widget is 
called 'rulerNM' and 'requires' some adjustments in NavTool.dbf. (Without 
the adjustments in NavTool.dbf it works also by the way, quick and dirty)
It doesn't work in JSAPI mode, if you want it to, you will need to modify 
"ConvertUnit" in cwcjsapi.js.

Copy the dir rulerNM to your widgets dir, if you put in nav_enhanced.html 
the following lines..

<td><cwc2 type="RulerNM" image="icons/icon_ruler.png"
visible="true" styleresource="NavButtons" imagetip="Measure Distance"
imagewidth="24" imageheight="24" toolset="Navigation" units="Nautical
Miles">
               <image state="normal"/>
               <image state="selected"/>
               <image state="hover"/>
             </cwc2>
</td>

.. it will work (remove the normal ruler code in nav_enhanced.html , because 
they bite each-other  :)

Cheers,

Jan
