fixes for minified version

I fixed the obvious stuff, i.e. use index.html instead of debug.html. 
Also I did add the absolute path to codrova.js which might be necessary (not 100% sure, but won't hurt).

I found an issue in system-ext which I also fixed.
Ok, with the help of inspector I got it working on the OWO emu now. 

I also renamed the service to org.webosports.service.update. That is more in line with the other system service. Sorry for the confusion...
