v0.0.3

Added

• Wait when doing "yank line" when using a remote shell (ssh, mosh) to
  ensure screen is updated.

Fixed

• Handle yank-line when used on the last line of buffer: copy multiple
  lines.
• yank-line never yanks 'newline' char for multiple-line commands in
  shell (this is actually tmux/bash bug).

Updated

• Code cleanup.
