add wburg.css to nwbrg deck.html

The Würzburg default css file is not included in the deck.html template found in nwburg resource directory. It is included in this call:

$for(template.css)$
  <link rel="stylesheet" href="$template.css$"/>
$endfor$

However, this is overwritten when custom css is included in decker.yaml.

For example:

resource-pack: exe:nwburg 
template:
  css: samantha.css

The left side shows with custom css defined, as above. The right side shows when this is commented out. This css file is empty.

I would like to add the following line to deck.html in the nwburg directory in Decker 13.4 and Decker 14: <link rel="stylesheet" href="$decker-support-dir$/css/wburg.css">

Should I make a pull request and do this myself?
