Scan for hidden SSIDs

[fhunleth]

It looks like you're forcing scan_ssid=1 even for networks that don't need it.

The wpa_supplicant configuration documention says this:

# scan_ssid:
#   0 = do not scan this SSID with specific Probe Request frames (default)
#   1 = scan with SSID-specific Probe Request frames (this can be used to
#       find APs that do not accept broadcast SSID or use multiple SSIDs;
#       this will add latency to scanning, so enable this only when needed)

The "enable this only when needed" worries me. Can you update to only set scan_ssid: 1 for hidden networks?
