Random (nice-to-have) stuff to fix

[ick003]

• Startup ovscouter with no argument and hability to fill the teams & lineups on start
• Add setter calls to setter action on reception
• Add ball trajectories to court module
• Playback the video at more or less than x1 speed
• Button to display list of attack codes tble / plot
• add set scores to scoreboard overlay
• user manual
• allow user to define the court reference on startup if they don't provide it
• allow the user to save the court reference into the video file, if it's all running locally
• Have the switch serve button next to the court module
• When serve/attack end point is out of the court, automatically propose serve/attack error
• Display score / set number somewhere? (not sure exactly where would be ideal...)
• support remote videos (maybe including Youtube?)
• add a demo function with bundled so that it can be tried easily
• refine the theme, once the UI design is a bit more settled
• ability to specify prior information (dvw files, or a tibble of plays data)
• attack error type (in net, out long, out side, etc)
• don't allow setter dumps on third contact in reception phase
• option to scout without attack codes (either just the player and start location, or maybe with tempo as well)
• plotting the ball path on the court diagram causes that plot to be re-rendered after each action, which slows things down noticeably. Rewrite the court diagram module to use base graphics, which will be a lot faster (or some other solution)
• option to restart from recovery rds file
• ability to set options (e.g. scoreboard, showing ball paths on court diagram) from within the UI
• rotation buttons when entering lineup so that the existing lineup can be rotated plus/minus one position
• plays table optionally be shown as a plain-language interpretation of each contact, rather than dvw codes

As of 42f9ddb it should be possible to start with just dv_create(teams = c("Home team name", "Visiting team name")) and enter everything else in the app. Not properly tested though.

Have done the serve error proposal when the ball is out of court, but not (yet) attacks, because not sure whether ball off hands (and either out, or dug from out of bounds) will be more common than the ball directly out (attack error). Needs discussion/thought.
