[keps] Correction/Additions to AMSAT KEP Distribution for 5-26-2016

Opps! NORAD CAT ID 41476 is named STMSat 1. I confused the name with SAMSAT which is non-functional at this time. Thanks to Nico PA0DLO.

Also I have added the following to this week's distribution: MinXSS - NORAD CAT ID 41474 CADRE - NORAD CAT ID 41475 NODES 1- NORAD CAT ID 41477 NODES 2- NORAD CAT ID 41478

Note: I try to use SpaceTrack names, when possible, to avoid confusion later on.
