This version fix an issue with the annotations metadata cache for
autowiring

Prepare the LaTeX to produce MathML by fmath converter, better
extraction of oMath to inline the equation in Word, fix a rare case of
single choice not being outputed

And some performance optimizations.

- Move topic edit buttons to the list of topics
- Only one view to edit topic and organizers
- Organizer selection in a multi dropdown menu
- Help buttons to initial values

to have the advantages of both:
- Nice GUI of the selection view
- Table display of the edit view

Remove the default passed value (false) if the cut value is not choosed
as mode to calculate passed / failed. Finer default correction mode in
course element after chossing a test (grader if grading enabled, manual
if test has manual by coach defined...)
