Add sort functionality for poll lists

[markusphil]

I already implemented sorting options for the questionlist and created some helperfunctions. This could be easily adopted for the poll / template list.

But maybe you have a better idea for the sorting functionality =)

Hi, I'd like to give this issue a shot

[markusphil]

Of course! just go ahead and let me know if you encounter any problems 😊

@markusphil so I have the app up and running locally. I'd like to get the requirements right:
I see a basic filtering is implemented on the poll list already (see screenshot attached). You mention a question list that has the desired filtering already, but while I can see the view file QuestionList.vue I can't seem to find it used in the application right now, is that correct?

I tried to generalize the "FilterBar" so it can be used with all available lists. The sort and filter logic itself is contained in the list components. The QuestionList.vue file is one of this components and it is used on the CreatePoll.vue View (it's the list on the left side).
