Merge branch 'terencehill/scoreboard_update' into 'master'

Scoreboard update

Scoreboard:
* limit size of player names and relative column; scoreboard width is now based on this value
* limit scoreboard height and therefore number of players displayed in the scoreboard, display remaining players with primary scores in the last row
* compact spectator list by displaying multiple spectator names per row
* display an empty scoreboard in the beginning in DM too

Rankings:
* limit name size and if there's enough room split rankings into more columns
* center text vertically and add padding to both sides of each column
