XDG and shared-mime-info for .robot files

[Akselmo]

Hi, we'd like to add custom icons for .robot files in KDE Breeze icon set. However, this requires that the .robot files have their own shared-mime-info, such as text/robotframework or something similar.

However, one can't create an MIMEtype for an extension we don't control, of course.

Here's more information about shared-mime-info: https://www.freedesktop.org/wiki/Specifications/shared-mime-info-spec/

If I understand this correctly, RF would need to install it's own MIMEtype during pip install, with xdg-mime. There are probably alternative ways too.

This would also fix an issue of .robot files being handled as .patch files by default because of the *** Header *** parts of the file.

Any interest in this? 😄
