Subject: [PATCH] [IMP] point_of_sale: posbox -> IoT Box and IoT Box image

- posbox -> IoT Box
- added scripts for server configuration and step by step wizard
- start Firefox browser on screen with specific url
- captive portal configuration with nginx and dnsmasq
- enlarged /tmp folder
- Removed dhcpd server as hostapd handled that already
