Copy paste on iOS?

**Is your feature request related to a problem? Please describe.**
I'm frustrated when I have something in my clipboard on my iPad but can't paste it into my Moonlight streamed dekstop.

**Describe the solution you'd like**
Ideally copy and paste would "just work". Cmd+C on the iPad, Ctrl+V or Ctrl+Shift+V (depending on the app) on the desktop. Or vice versa.
