Fix compatibility with SemanticForms versions > 2

* Increased MW supported version to 1.17 (ResourceLoader is neeeded by SF)
* Also adds id="sfForm" to the form generated so it works properly with
  SemanticForms
* Remove invalid scripts added from older SF versions, SF seems to load them
  on its own now.
