Show league name when deleting league.
Slight refactor of core.trade to allow for display of the 'value' of each team's offer.
Player value is logarithmic when making trades, so it is harder to steal top players from AI teams.
Beginning work moving/refactoring db.getPlayers to player.filter
Rename player variable to p so that core.player can be conveniently imported.
Replacing db.getPlayer with core.player.filter in views.player seems to work.
Initial tests for core.player.filter. More to come.
