This feature wraps both page ends, meaning that users can jump from the
first page to the last page, using the previous page reaction,
while using the next page button on the last page brings you to the
first page.
Resolves#233.
This commit fixes#75, where the player doesn't start playing when
it's been previously paused.
This may happen when a user pauses the player, clears the queue or skips
all songs and another user tries to use the player later.
