lots of changes:

- change how we handle modules for services in the VM
- fixed wtv-disk:/sync always failed the first time
- implement production-like wtv-star handling (when a service port becomes unavailable, it requests the url over the wtv-star port to show an error page)
- renamed WTVDownloadList.js to WTVDisk.js
- a bit more work on WTVNews (created class)
- probably more stuff I can't remember
