device name is confusing

[andysc]

Device name is currently set to KettleCompanion
but we've agreed that's the name of the little kettle, so we need to call it something else.
Suggest KC_SmartPlug but am open to suggestions.

This only became apparent when I was writing the configuration instructions, and I was talking about KettleCompanion SSID for the SmartPlug, and thought dat's not right.

I realise I mean the SSID it shows in AP mode.

I think this is addressed. AP comes up as SmartPlug_FactoryDefault and I've changed the friendly name
