Allow admins to edit eval template question order
Prevent admin from giving many q's the same pos
Comment jQuery for autoselecting question pos's

- Temporarily comment the jQuery that autoselects question positions
  based on what the admin has selected, as it doesn't yet work

- The positions overlap when, without submitting the changes, the admin
  changes the position of a second question to be what the first one has
  ended up as (from the first (round of) selects); this needs to be
  fixed

- Now: this is a low priority feature
