Image and video upload

[Starbugstone]

Allow the upload of images and videos to a trick

[Starbugstone]

Don't forget the default images. Aslo need to allow the user to chose which image will be up front.

Will need to take care of the image uploading without vichs uploader. Else the project might not be valid.

• First off, use vichs uploader in main branch
• look into creating my own uploader bundle with vichs's functionality.
• Replace vichs calls to my own
