Ability to set advanced WiFi options

[DavisNT]

I would like to propose two additional checkboxes for WiFi

• Force WPA2-AES (for enhanced security)
• Connect to network even if it is hidden (this is always enable currently)

Additionally I suggest always adding key_mgmt=WPA-PSK directive.

Force WPA2-AES (for enhanced security)

If enabled should add the following directives

proto=RSN
pairwise=CCMP
group=CCMP

Connect to network even if it is hidden

Should set directive scan_ssid to 1 if enabled and to 0 if disabled.
