ragconnect.mustache

- use local version of jastadd with fixed flush-inc-attr event
- use changed jastadd to check params of that event (the index of the NTA in this case)
- fixed cleanup of ragconnect-observer
- disconnect now is successful, if one sub-publisher removed the given token
- still todo: finish test, check "check" method
- use packaged jastadd version once it incorporates local changes
