[studs-user] New HTML tag for checkbox

[Greg H. <sc...@im...>]

I've created a new tag for an HTML checkbox.  The source is included  
below.  The only other change required is that you update WEB-INF/tld/ 
studs-html.tld to include an extra tag entity:
   <tag>
     <name>checkbox</name>
     <tag-class>studs.taglib.html.HtmlCheckboxTag</tag-class>
   </tag>

I haven't tested it heavily, but it is currently working for my  
project.  This was a little bit trickier to get working than the  
password tag, but not much so.

In case the text below gets mangled, the source is available at  
http://scsibug.com/HtmlCheckboxTag.php.txt

Thanks,
Greg Heartsfield
