Media plugin hardcoded upload url

Sorry, 
but I tried to install the spud cms w/ spudmedia (on localhost it went fine) but once deployed on a full domain name site it breaks, I think we should reconsider:
**baseUrl:"http://localhost:8080${SCH.servletContext?.contextPath ?: ''}/${mapping}"**
in _SpudMediaGrailsPlugin.groovy_ @ https://github.com/spud-grails/spud-media/blob/master/SpudMediaGrailsPlugin.groovy
