WiFi selection screen, allowing to connect to WiFi of choice:

• Listing the available WiFi networks, their signal strength and encrypted status
• Choosing a relevant WiFi network
• Asking for password if the WiFi network is encrypted
• Showing success or failure on connection attempt

@syounger Please start testing, contact me on any question.

The whole page reload / error display done in quite convoluted way, once working a good idea will be to rework to AJAX-based mechanism.

Moving back to me to test according to Zvisha requirements:

• WiFi works without ethernet (overnight test).
• Ethernet with DHCP/Static IP works on boot, regardless of WiFi configuration.
• Cable out/Cable in works (should restart cgminer)
• Disconnection of ethernet cable restarts machine after 5 minutes.
