* eframe README: explain how to enable copy/paste
* Implement Debug for a couple of structs
* Code cleanup
* Better docs
* profile ron serialization
* CI: Allow "exclude from changelog" as the only label
The problem is that when we call Context::create_viewport_sync can be on any thread because egui::Context is Sync + Send but the backend is not!
So we want the callback to the backend to be thread local!
The problem that this adds is that now you cannot create more then one egui::Context,
because the thread local variabile is static and i don't know how to store a non static LocalKey on egui::ContextImpl

When exiting my application, it would freeze for around a minute waiting to finish writing ca. 40MB to file storage.
Some quick profiling revealed that it was spending all that time in `File::write`,
presumably making a large number of system calls writing tiny amounts of data at a time.
We can avoid this by buffering writes using a `BufWriter`, just like we already do with `BufReader`.
With this change, my application takes around 1-2 seconds to exit, with the majority of that time spent serializing `ron`.
I'm sure there are further potential performance improvements there, but this is already an order of magnitude or two better.
I also fixed the call to `log::warn!`, which was using incorrect formatting syntax and not including the error message.
