Better list display algorithm

When an actor is in episodes of a series, the listing gives the series name, then lists the episodes.  If the actor is in more than five episodes, the first five are listed followed by a line with "Show all nnn episodes."  Clicking the button causes the other episodes to be listed.

Note what happens if the actor was in exactly six episodes.  The first five are listed, followed by "Show all...."  Clicking the button replaces the "Show all" line with the sixth episode listing -- in the same amount of space.  The algorithm should be changed to make that automatic: If the actor is in up to six episodes, list the episodes.  If the actor is in more than 6 episodes, list the first five followed by the "Show all..." line.

Makes the listing slightly more user-friendly, using the same amount of screen space, and requires minimal coding.
