Prevent linking to the self referencing Waypoint file.

[RalphMRivera]

When creating a Waypoint file, the list references itself. Is there a way to prevent this? For example, assuming I have the following:

Spice (folder)

• Jessica (file)
• Leto (file)
• Paul (file)
• Spice (file) <--- Waypoint

The Waypoint file, "Spice," would list the following:

• Jessica
• Leto
• Paul
• Spice

You don't need the file to link to itself.
