Add notification image when everyone finished voting

Currently, when you finished all the voting stuff by clicking on the vote button, the image won't show up. It will show up only when you open a session that everyone has voted.
It behaves like this because the image shows up during building layout when the request finds out that every requirements has been voted by everyone. 
To make the image show up immediately after that last vote is finished, i think we still need to find out from GUI side that whether every progress bar is full.
