Tag implications: various balls → ball

These balls all should imply ball, but do not:

• beachball 693
• billiard_ball 1
• bowling_ball 10
• exercise_ball 13
• golf_ball 11
• soccer_ball 93
• tennis_ball 33

Some other sport-ball-related tags should not imply ball:

• football 19
• baseball 281
• basketball 199
• pinball 3
• softball 3
• volleyball 212

Because, for example, "baseball" is the name of a sport, and the scene might depict the sport of baseball without depicting the baseball ball itself.

To me, the lone word "ball" strongly suggests a game ball or play ball, so I think that other tags for ball-shaped objects such as meatball or hairball should not imply ball.

Put a " _ " dash line in between the tags

A baseball is a ball used to play baseball not a ball used to play base. Madlibs your way through the other ones.

We could do nball_(ball) as there are cases where you would want to tag the ball but not the game such as a ball in someone's bedroom.

I think instead of using nball_(ball) it would be better to go with nball_(object), to be more inline with other object tags.

_(object) for the actual round things you throw/kick/hit and keeping the base tag for the sport gets my vote as well.

I did the -> ball implications for the first group.
