This update includes many changes. E.g.:

• New question types (one-to-one sorting, click questions, free text)
• Bounding box annotation type
• Updated task functionality (select task type and more annotation options when making task)
• Updated look of the slide image viewer (e.g. hiding the slide info card, option to toggle annotations)

Can you please review this? In particular:

• See if you find errors/bugs
• Should we do any design/interface work before merging these or just put this on our to do-list?
• Any other feedback?

This PR/branch includes changes from multiple other branches (including task_course-next-button and slide-viewer-accordion), and that PRs for these branches may be closed if this PR is accepted

Here are some to do's that I see:

Questions

• [x] Should remove Next task button as long as only multiple choice questions are included in the pool of tasks that are looped through

Click question

• [x] Remove text input from annotations in the click questions

Course

• [x] Add styling/colour to the currently selected course tab
• [x] Editing task from course should direct you back to the course, not to task list

The following TODO's from above have been skipped for now, but are added to the project board to be handled later:

• One-to-one sorting: Feedback to the user is only given as coloured alternatives. Should give feedback with symbols/text as well (for accessibility reasons)
• Click question: Since double-click is used for answering the click questions, this action should not zoom the WSI
• Free text question: Clicking Submit with emtpy text box reloads the page, but doesn't give any feedback to the user (e.g. "You haven't answered the question"). Maybe the button should say "Check answer" or "Display teacher's solution" and the given text solution should be displayed even if no text was answered?

Okay, I'll merge this now
