Improve usability to create question catalogs

[leucoryx]

• easier change of question order (not be memorizing order number)
• less number of sides
• links of questions and option sets should be visible from both sites

[jochenklar]

The third point is solved in addffba.

[jochenklar]

As of RDMO 1.4 the order number is displayed in the list view.

Unless we refactor the whole management interface, no further improvement can be done here.

[MyPyDavid]

the whole management interface is refactored.

The order is editable by drag&drop

• easier change of question order (not be memorizing order number)

The order will be displayed again with this PR

What is meant by these points? (single page?)

• less number of sides
• links of questions and option sets should be visible from both sites

[jochenklar]

I think that was about the 6 different management pages. Can stay closed.
