Hints for kjots in main

Hints

• asv-description-first-para-too-short
  :66 - KJots organises all of your notes into separate books.
  The first `description/p` paragraph of this component might be too short (< 80 characters). Please consider starting with a longer paragraph to improve how the description looks like in software centers and to provide more detailed information on this component immediately in the first paragraph.
• asv-screenshot-media-url-not-secure
  :274 - http://kde.org/images/screenshots/kjots.png
  Consider using a secure (HTTPS) URL to reference this screenshot image or video.
• asv-desktop-app-launchable-omitted
  -
  This `desktop-application` component has no `desktop-id` launchable tag, however it contains all the necessary information to display the application. The omission of the launchable entry means that this application can not be launched directly from installers or software centers. If this is intended, this information can be ignored, otherwise it is strongly recommended to add a launchable tag as well.
• asv-content-rating-missing
  -
  This component has no `content_rating` tag to provide age rating information. You can generate the tag data online by answering a few questions at https://hughsie.github.io/oars/
