More versatility for Quiz Exercises and Drag and Drop

[nic-kie]

Is your feature request related to a problem?

a) I can't find a use case for quiz exercises outside of the start of a lecture. All other exercise types can be done both during a lecture and as a homework.

b) drag and drop quiz exercise does not work well with an exercise where for example you have to draw the individual pixels of an image.

Describe the solution you'd like

a) An option for quizzes to not run on a timer. i.e. no time constraints once the user starts the exercise apart from the deadline.

b) Drag item reusability in drag and drop, and better editing features, such as copy pasting selected fields, deleting multiple at ones, etc (like ctrl + left click on Apollon)

Describe alternatives you've considered

Manual file submission exercises
