Describe the bug Double clicking a .tx file should open it in Tiled.app

Yeah, that's a good thing to look into. I'm not sure if it's enough to just add a line with tx to the Info.plist file, but that'd be a start at least. Probably tsx, as well as tmj, tsj and tj (more specific extensions supported by the JSON format) and tiled-project should be added there as well.

It would be nice if the Windows installer also associated those other formats with Tiled, ideally optionally. Looks like only TMX is registered: https://github.com/mapeditor/tiled/blob/3d8724f91ba53d7c1d245b5a8f778662a7aa5d0d/dist/win/installer.wxs#L142-L147

It looks like in some versions of Windows (or at least in some combinations of settings?), manual registrations display a different, less clear icon than the built-in association, so even though it's fairly easy to make the associations manually after installing, it would be nice to have the installer make them. Screenshot from Mitsuru Tenma on Discord: On my Windows manual associations look fine, but I can see why they'd be suboptimal on theirs. I imagine it's just some settings difference, but Windows doesn't make it easy to find xP
