Release v2.20

Here’s some presents from us for some merry holidays:

• Animations: Reworked the underlying animation engine to prevent stuttering animations.
• Archived Cards: Non-done cards that got archived get a dedicated color so they’re easier to differentiate from their non-archived counterparts.
• Attachment Viewer: Now includes the title of the images.
• Github/Gitlab/Bitbucket Integration: You can now mark multiple cards as fixed by including e.g. Fixed $123, $124, $125 as part of your commit message.
• User Management: An updated look and improvements for bigger user lists.
