Event for when a player clicks to view a Pin

[Shemp]

I would like an event when a player clicks on a Pin to jump to its location in Remote View. This would be similar to on_player_clicked_gps_tag, but would return the LuaPin instead.

This would nicely complement the recently added LuaPin interface.

-------------------------

It may also be useful to have events for:

• Adding a Pin (optionally via LuaPlayer::add_pin as well)
• Editing a Pin
• Deleting a Pin

But these are less necessary because the Pins can be monitored during an on_tick event, or you could shadow the add_pin input with a CustomInput to simulate an "Add pin" event.
