Little tweaks in ProxyLCD

I found one annoying issue – when sending only number it crashes.

Crash was easy to fix but unexpected. While converting int to json, Python just convert it to number. I’m not sure if this is a bug or not. But I added additional check.

Lets make an app a little more talkative. When started it prints some useful info:

Config loaded. Starting app
TCP port:  5054
Broadcast IP:  192.168.1.255
Broadcast port:  5053
LCDs:

Info       | rpi1       | 20,4    | +      | charlcd
damaged    | node-2     | 16,2    | -      | charlcd
