Add new display mode for individual tounaments (optimized for regional tournaments with small dispalys)

[tlehr]

This pull request adds the individual tournament display to BUP. The display is a display that is designed for (regional) individual tournaments.

The display is based on the display for teams and has the following features:

• The display can show the field number, the discipline and the round of the match (between the player names).

  • All new fields are optional and can be switched on or off by parameter or URL.

• If a timer is displayed on the field, it will be clearly highlighted. There are a number of additional modes for the timer that can be activated in BTS (see https://github.com/phihag/bts/pull/45 ).

  • When the timer is about to end, it can change color, just like on the tablet.

• An attempt is made to display the players' names as large as possible, as regional tournaments often only have smaller monitors available.

  • By default, players' middle names are suppressed to make the names easier to read.

• Since matches often take place without a referee (and a player who is not playing operates the tablet), there is now an option to underline the player who is receiving :

• Display in the second set

The documentation has been adapted to the new features where necessary.
