Copy/paste with system clipboard is not working in the UI

[Kryptos-FR]

Copying/pasting from within the UI should interact with the system clipboard. Currently, only pasting from the clipboard seems to work.

Additional context In standard egui implementations, there is a specific "clipboard" feature. See:

• https://github.com/emilk/egui/blob/master/egui_glium/Cargo.toml#L32
• https://github.com/emilk/egui/blob/master/egui-winit/src/clipboard.rs
• Look for copied_text: https://github.com/emilk/egui/search?q=copied_text

Hey team! Please add your planning poker estimate with ZenHub @guusw @sinkingsugar

There's already some wrapper code to retrieve the copied text to the clipboard but it has to be added to the rust context still. It's on the InputTranslator class
