[FIX] firmware: 1.3.1 / 1.3.2 Styling changes

Do not react to RAD messages for IKE.

Fix wrong reporting of PAUSED status.

Handle initialization of new config storage on Upgrade and restore.

Make sure we initialize connected status properly on BT STATUS call to avoid race conditions. Related to c33c58432358a407e88d5dcda222ea5208eb0810 change.

When preferred Device MacID is stored, do not connect to other paired devices. Should select from Device Menu to pick new preferred device. TODO: could probably ignore preferred after some time of not being present (5-10 sec).

Store last connected device in EEPROM. Store selected device from menu in EEPROM. Reset Last MacID on pairing clear.

Add support for storing byte-arrays in eeprom (eg MacId of last device).

Silence the logging for stable code.

Do not overwrite the BT connection state on every new BT message.
