order pre-selected items

[Remi-Gau]

for ARTEMIS and COBIDAS there are questions where users have to:

• select items ("which preprocessing steps did you perform)
• specify an order for the previously selected responses (in which order they have been performed

At the moment we are using the fact that the "select widget" returns the selected items in the order that they were selected, but this is more using the current behaviour of that widget and it is not necessarily a proper feature, so this would need to be formalized.
