Plai v1.9

Release notes for v1.9 (changes since v1.8).

Mesh & radio

• Channel activity detection — detects activity on the channel (#3).

• Hold CTRL for additional packet information.

Nodes app

• Remembers last sort order and selected node across sessions.
• Traceroute success uses a dedicated sound.
• Channel sounds — new notification options and an extra channel alert sound.

Stats app

• System tab shows firmware version; all tabs use scroll where needed.
