Support for detailed info about task

[blcham]

As a user of the component I would like to see info about the task when clicking on it. I assume some kind of modal window would show up upon double click/on hover.

Moreover, @PluharVit I feel like this popup should be customizable. It could have some kind of default, but you should be able to hook here your own react component (into the tree of the pop-up).

Should include:

• percentualne kolik tasku bylo spraveno
• komu ten task patri (scope)
