[IMP] website_forum: frontend improvements and corrections

This commit adds new features and corrects some others in the frontend
of website_forum app.
- In the "about" section of a forum, use the s_accordion instead
  of a custom one for the first 3 elements, the last one is on a
  new page accessible from a link below the accordion
- Cut the description after a specific amount of characters in the
  page where all forum are listed
- In that same view, create options that show the number of post
  and the last post a forum has. Create an option to render forums
  in list view
- Allow the user to cancel his vote (down or up)
- Hide the answer box in the post view. Make it appear when the user
  click on the "answer" button
- Use a JS public widget to validate a Post form (new, save, comment)
- Enable the modification of a forum's image from the frontend
- Hide Solved/Unsolved categories in "Discussion" forums
- Disable the possibility to add snippets to an answer
- Corrections of tours that broke after these modifications
