Text field keyboard shortcuts broken on Linux

[nyanpasu64]

Running RmlUi master 747d73c built from source, on Linux KWin X11. In the demo app's "Forms" tab, I cannot use keyboard shortcuts like Ctrl-C or Ctrl-V in text areas; it instead types "c" or "v". Copying and pasting works on Windows.

We haven't implemented system clipboard in the Linux and macOS shells, now they only copy and paste internally in the application. This feature should be a good exercise for someone familiar with these platforms.

With that said, filling of the text (c/v) should not occur when typing a shortcut key. Thanks for letting me know, that one should be fixed now.

I think we should open a new issue for the system clipboard feature if this is desired. The main issue here is considered the unintended c/v text pasting and should now be fixed.
