This is an implementation of network sharing (aka 'Hotspot').
The new 'Use as hotspot' button lets you use a wifi device
as a hotspot for sharing network connections with others.
Currently, the panel generates a ssid based on the hostname,
sets the security to WEP, and generates a random key. These
parameters can be edited afterwards.
It is currently not possible to show how many connections
are using the hotspot. Apart from this, the implementation
is pretty much complete.
