Brian Osman ba3e8f9779 Improve Viewer on UNIX
- We were using the wrong keycodes for letters, so we never triggered
  undo/redo/copy/paste in response to Ctrl+Letter combos.

- ImGui comes with system clipboard support on Windows and Mac, but not
  UNIX/Linux. I added a bare bones X11 implementation, enough to support
  copying and pasting text in and out of the ImGui text windows. There
  is a bit of a delay when pasting to another program, probably because
  we're not running a dedicated thread to handle those events. It looks
  like we get a flurry of events before the real SelectionRequest.

- Note that this leaves the virtual clipboard functions on Window only
  implemented for UNIX. We could supply our own copies for Win/Mac and
  other platforms, if anyone really cares.
