Fixed bug with Clipboard on Wayland

[skyride]

There's currently a bug with the Linux release under Wayland where the copy/paste functionality doesn't work. It doesn't reliable access the clipboard as expected, so it'll silently fail to copy from clipboard, and most applications are unable to access things paste to the clipboard.

This PR fixes that by forcing it to use the actual Clipboard instead of Primary. Primary is a neat feature, but the behaviour is inconsistent if your application isn't built with its special usage in mind.

Testing

I've tested this on Wayland Linux, but I'd suggest double checking it works as expected on Windows and Mac before merging. I'm trying to see if I can get some help with that.

Well that's an issue for me. I have 2 laptops, both have some flavor of linux. I might test windows build under wine, but I don't think it's a good idea for this particular change. So if you can, please try it out.

Alternatively, I can just poke friends of mine to try it and see if it works.

edit: also I am using gnome on wayland, never had issues with copy-paste

I will merge and test windows version via wine. Unfortunately, no mac device to test it on, but I will just be ready to make a quick fix if it breaks anything.

Nevermind, it broke clipboard even under wayland for me. Import works fine, export does not

I did some "fixes" in 84fbc0a, they reverted:

• use of new clipboard object instead of global one
• flush call

With either of those in place, copying does not work at all for me under wayland.
