Free Software Virtual Singer Update

I've debianized the vConnect-STAND synthesizer. It is now hosted on https://devel.trisquel.info/isengaara/vconnectstand and can be used with JCadencii, which is already in the Debian repositories and therefore in Trisquel. The package in recent Trisquel versions contains a patch written by me to make JCadencii work with vConnect-STAND.
