Explain how to use with KDE

[ChrisCheney]

Since its relatively simple to use this plugin with all of KDE it might be helpful to explain how to do it for users who need it before its added officially.

1. Install updated shared-mime-info (1.10)
2. Create files for the file format for KDE:
   /usr/share/kde4/services/qimageioplugins/heic.desktop
/usr/share/kde4/services/qimageioplugins/heif.desktop
/usr/share/kservices5/qimageioplugins/heic.desktop
/usr/share/kservices5/qimageioplugins/heif.desktop
3. Add it to various areas that need it, eg:
   /usr/share/kservices5/imagethumbnail.desktop

Then it works with everything. 👍

This sounds great! Could you make a PR? I have limited time right now, and I don't have a KDE test environment ready to go.

Instead of adding instructions, though, I think it would be best to include these files and install them as part of the build. They would also be part of the packages that way.

I don't think that would create any additional dependencies, since the KDE files would just be ignored if KDE is not installed. It might conflict with a future version of KDE that includes these, but we already have that situation with Qt, which is a separate issue that should be addressed.
