Add the WLAN statistics dialog.

Instead of splitting the stats into two lists as with the GTK+ UI, add
everything to an expandable tree. This allows viewing nodes on more than
one network.

Rename the top-level Bluetooth menu item to Wireless and put the WLAN
stats dialog there.

The Qt UI matches SSIDs (WlanNetworkTreeWidgetItem::isMatch) a bit
differently than the GTK+ UI. Try to make the logic as plain as possible
since we'll likely have to update it in the future.

The addition of a custom BSSID address types means that we can't assume
that everything is AT_ETHER. Add routines for checking for broadcast
BSSIDs and comparing only the data portions of addresses.

Move PercentBarDelegate into its own module. Use it in
WlanStatisticsDialog.
