• remember-height was replaced with start-size, when start-size is set
  to video the main video starts directly with the native video size,
  before it was starting with the autofit size first and was only
  afterwards resized to the native video size
• on exit the window location can be saved with remember-position
• in the learn window of the input editor underscores were stripped
  because they have a special meaning in WPF labels
• fix for keys/input not working for MBTN_LEFT_DBL, MBTN_BACK, MBTN_FORWARD
• in the learn window of the input editor support was added for
  mouse left, mouse left double, mouse mid, mouse forward, mouse back
• libmpv was updated to shinchiro 2019-07-07
• when border is none it wasn't possible to minimize the window from
  the task bar because this is the WinForms default behavier. This
  was fixed by calling Spy++ to the rescue and adding WS_MINIMIZEBOX
  in CreateParams
