v0.8.1

Fixed

• Do not show the last pick information when selection was changed via the terminal.
• Update the selection notification when the displayed unit changes.
• Fix backdrop material so it works for sprite-based modes (B&S, VDW...)
• Fix a bug in Cartoon geometry which led to bad raycasting performance.

Internal

• Visual regression tests are now run in headless Chrome. This allows lowering error threshold and
  comparing results obtained on different graphics hardware. It is a big step towards distributed
  testing in cloud.
