[Feature requested] Make it possible to add multiple CRcles to the same task

[kpachhai]

This may require a longer discussion but there are cases where a particular task belongs to multiple CRcles. For example, I want to create a task to explain elastos carrier. But, I want an article and a video to go along with it as part of the same task because it's the same task and the budget comes from the same pool.
So, in my opinion, it makes perfect sense to be able to attach multiple CRcles to the same task.
