Give the user more information when using WiFi

Inform the user about these case:
 - A NEx.hda is set up but no WiFi SSID in ini is set
 - A SSID is set in ini but no NEx.hda exist on the SD card
 - Inform the user when WiFi authentication has failed
 - Inform the user when no SSID is found
 - Inform the user when connected but no IP is given
 - Inform the user when a general WiFi failure occurs
 - Reword "BlueSCSI Toolbox enabled = 0/1" to "BlueSCSI Toolbox enabled/disabled"
