It should be translatable via Transifex, but currently isn't even though Transifex supports that file format. We just need to import dolphin-emu.desktop as a new resource.

There's a small issue with how "tx pull -a" downloads the translations: It creates a single .desktop file for each translation. I don't think there's a good way to make it download all translations into a single file, but https://www.redhat.com/archives/fedora-trans-list/2009-August/msg00040.html (very roughly) outlines how to merge multiple .desktop files together, which should work for us.
