Enhancement : display WiFi bitrate, transmission power and signal level

[Bbox77]

It is based on this other request . Those values are displayed under Wifi on the Status tab and in the same graph on the Statistics tab. It is based on wlan.conf

The proposed code doesn't work with every Wifi Adapter. For example on mine the Bit Rate is displayed on iwconfig as "Bit Rate:54 Mb/s" instead of "Bit Rate=54 Mb/s" as your code seem to expect. Also, my wifi adapter doesn't support power management, and it showed up as "Tx Power: dBm" on the status page, I like "Tx Power: 0 dBm" more.

Here is an improved version:
