"PriorityGameModes" and "ForbiddenGameModes" column properties in SCORINFO

I added two more column properties to SCORINFO:

• PriorityGameModes: a list of game modes that are excepted from the column's game/earn type checks (i.e. these columns have more priority). The column will still be active in the listed game mode(s) (provided that they're also listed via GameMode, if applicable), even when they're incompatible with the column's game/earn types.

  • Example: in duel, players earn frags, but the "wins" column normally appears only in game modes where players earn wins. This property allows the column to appear in duel too so players can see how many wins they have (addresses https://zandronum.com/tracker/view.php?id=915).

• ForbiddenGameModes: a list of game modes that the column can't be active in.

  • Example: in domination, teams earn points, but the players themselves don't. It's not important to show the "points" column in this case (addresses https://zandronum.com/tracker/view.php?id=4288).
