Issue #2646116 by eelcopeacs: Fixed sequence questions not working correctly. Closed Question sequences can now be used correctly. Note that a Closed Question sequence is treated as one question in the Proteus quiz

Corrected for topics (objectives) that were related to a user/question but not to a quiz, resulting in an error message

Corrected resetting of the quiz levels, the quiz current status in now also reset, and when showing the progress after correct answer, only the quiz topic related score gain is being shown

The progress table, default only shown to the teacher, can now be shown to the student by configuration checkbox and the link to the next question is replaced by a button next to the answer button

Issue #1162382 by M_i_c_h_a_e_l, eelcoPeacs: Remove the "step choice" feature. Added this feature as a configurable item to the Drupal 7 version of this module. This means that now you can configure a step size to use during a quiz
