Keyboard input should bring the cursor back to the input line

[matt-cahill]

When selecting text the cursor stays in the position the user puts it, after this any keyboard input is ignored unless the cursor is manually returned to the input line. I believe expected behaviour is that the view would scroll to the input line and text input would immediately begin.

I have this working for typing into stdin while commands are running (PR #85). It should be simple to apply it to input while no commands are running as well. I'll take a look at this when I get some spare time.

Thanks Ian, that PR looks like a great overall improvement.
