On Linux, copy and paste now work even without wl-copy, xclip or xsel installed.
What's wrong with this entry?
A native clipboard component is now built into the binary. On Linux, if none of wl-copy, xclip or xsel is installed but DISPLAY or WAYLAND_DISPLAY is set, copy and paste now fall back to this built-in component instead of failing.
- It joins the already-embedded image and audio components, with on-disk copies available for x64 Linux.
- Selected only after the three external tools are probed and none is found.
- If a write through the built-in component fails once, that failure is remembered and the component is not chosen again for the rest of the session.
