Display current score on pairings page

[hopffgam]

Suggestion from Slack. On the pairings pages the score of each player (960, LW) or the current team score (4545) should be displayed so that it is more obvious what is at stake for the players.

Note: for 960 and LW there would need to be a decision how to handle late-join points that are used in the intermediate standings and for pairing purposes, but will be deducted for final standings. My assumption is that we want to ignore those on the pairings pages.

Additional note: those scores need to be persisted on the pairing object, or at least always fetchcing them from the current standings at the point where a pairings page is shown would result in wrong scores.
