Andy Jordan 06e3b4bcb6 Add fixture to enable existing tests for screen reader mode 
Tests that depend on supported features such as menu completions, list
view, inline predictions, continuation prompt, and colors are skipped.

The "helper" module for running tests from the command-line and in
AppVeyor is minimally updated to not skip the new fixture.

A `BlankRestOfBuffer()` function implements the semantics of the `0J`
control sequence in the mock console.
