Problems found in setting up Catena 4450

[terrillmoore]

Russ Nelson had the following suggestions after setting up a 4450 recently.

• Split out the TTN configuration information into a separate page. It's too long for a "Note".
• Also add the note about "If you're in the US, use the us-west handler".
• Changing registration should be a note.
• In place of Changing registration, you should explain what the various blinks mean, and point people to the console.
• Tell them to add the Data Storage Integration, and the Payload Decoder.
• Then tell them to look at the Devices/Data page to see the data coming from their 4450, and that they should expect to see Activation once a minute until it succeeds, and then sensor data every six minutes
