Changes

• Query results are now sorted first by status (todo before done) (#83)
• Fixed a bug where a query would still list tasks from a file if the file did not include any list elements anymore (#86)
• Fixed a bug where a task could sometimes not be toggled (#87)
• Styling is now easier since ul (query result) and li (everywhere) elements of tasks have specific classes (#91)
  • ul: plugin-tasks-query-result
  • li: plugin-tasks-list-item
