Hi, Just downloaded the latest release(0.6.4, AppImage), and when executing it will ask me if I want to integrate DevDocs with my system. However, when I accept it, the following error is printed:

/home/barbiero/.local/share/applications/appimagekit-devdocs.desktop: error: value "devel;" for key "Categories" in group "Desktop Entry" contains an unregistered value "devel"; values extending the format should start with "X-" Error on file "/tmp/.mount_McyF2u/devdocs.desktop": Failed to validate the created desktop file

It might be something wrong with the AppImage build, so I switched to the .deb version as a workaround but I believe you might want to look into it. I'm interested in this in particular because the .AppImage is only 50MB in size while the .deb uses roughly 128MB(according to my /opt/DevDocs folder).

Thank you for your work.
