[PRQ#54217] Merge Request for vala-panel-sntray-git

rilian [1] filed a request to merge vala-panel-sntray-git [2] into vala-panel-git [3]: It will be merged with base vala-panel package. I am in process of removing other panels' support. It is unneeded now, they all have its own StatusNotifier implementations.
