Description
In the list of questions of a test (e.g. https://testing26.beeznest.com/main/exercise/admin.php?cid=1&sid=0&gid=0&gradebook=0&origin=&exerciseId=13), the question type is supposed to appear in the preview section of the question.
This is due to a shortcut used in Chamilo 1.* to use the question type string (e.g. UniqueAnswer) as a language term.
Given the fact that Chamilo 2 works with Gettext, a camel-case string like UniqueAnswer is not found as a translated term (it should be Unique answer).
The issue is that it is based on a table that is also used to find the name of the class (in the "PHP class" sense) of the question itself. See https://github.com/chamilo/chamilo-lms/blob/master/public/main/exercise/question.class.php#L46-L74
So this array should be redefined to add a new "column" with the translatable name, and any calls to it should be adapted to use the right index (e.g. get_question_type_name() should be modified to use [2] instead of [1]).
