* Get{Interface|Network|Service}() methods are now const.
* Added variants of Interface(), and Service() that are const.
* Added new BNetworkServiceSettings::IsRunning() convenience method that
reflects the status quo rather than the settings.
* GetMessage() now checks if the only existing address is the default
wildcard address, and then omits it in the message (as it will be
created by default, anyway).
* If it does not exist yet, the sshd user is created upon enabling
the service.
* Also, it now uses kMsgIsServiceRunning to determine the current
label/function of the enable/disable button.
* Added BNetworkInterfaceListItem that can be used by interface protocol
add-ons to represent their functionality in the list view.
* It will automatically update itself on changes, and will show the
specified label, and address, if any, as well as indicate whether or
not the family has been disabled (which doesn't work perfectly yet,
as IFF_AUTO_CONFIGURED is on the interface level).
* Therefore, the interface list item will no longer show the address,
but the type of the device instead.
* Introduced the BNetworkConfigurationListener interface that is used
to broadcast network updates to.
* Via the BNetworkSettings class.
* The static IP mode still requires an extra apply button.
* IP input is not validated at all yet, we could also automatically
fill in the network mask once the IP has been entered.
* You can now optionally specify a converter that does the actual
message to settings conversion, and vice versa.
* This allows for more sophisticated and custom conversions.
* Network now monitors all network, and network settings changes, and
will notify all add-ons about those changes.
* Removed the global apply button. Instead, the static IP configuration
now got that button. All other changes will be instant.
* Added (still incomplete) helper classes for the settings messages.
* The net_server now uses these classes for its interfaces, and services.
* Renamed service_address to service_connection, as that better matches
what it is used for.
* As experimental API class BNetworkSettings.
* Added add/remove methods for interfaces, and services, too.
* Moved the conversion of the wireless networks into the settings class,
too, so that it only gives out converted ones (but accepts both
variants).
* Completely superfluous and expensive for BListView items, and just
wrong for BOutlineListView items.
* Also increased the width of the item, as we must take the tree offset
into account ourselves (really, great API).
* The interfaces logic is within the main application, so is the
new interface view.
* Disabling/renegotiating does not work yet.
* Reveals a bug in some interface code; when you click on an ethernet
device first, there is no place for the wireless menu. When you then
press on a wireless device, it crashes in BMenuField code.
In the other direction, there is then an empty space.
* Fixed list item width reporting.
