airodump-ng: add manufacturer column to the clients list

[sighook]

Aircrack's airodump utility has an option --manufacturer:

--manufacturer : Display manufacturer from IEEE OUI list

Currently, it shows only AP (BSSID) manufacturer, but will be come in handy to see also connected stations manufacturer.

For example, sometimes due pentesting purposes is necessary to view stations manufacturer and to not disconnecting all clients from the AP, but only one/two/etc (the most vulnerable from the point of view of Social Engineering).

For example.

Before patching:

 BSSID             STATION            PWR    Rate   Lost  Frames Notes Probes
 XX:XX:XX:XX:XX:XX XX:XX:XX:XX:XX:XX -54    0 - 0e  0     1            XXX,XXXXX,XXXXXX
 XX:XX:XX:XX:XX:XX XX:XX:XX:XX:XX:XX -38    0 - 0e  155   43

After:

 BSSID             STATION            PWR    Rate   Lost  Frames Notes Manufacturer                    Probes
 XX:XX:XX:XX:XX:XX XX:XX:XX:XX:XX:XX -54    0 - 0e  0     1            Hon Hai Precision Ind. Co.,Ltd. XXX,XXXXX,XXXXXX

 XX:XX:XX:XX:XX:XX XX:XX:XX:XX:XX:XX -38    0 - 0e  155   43           Liteon Technology Corporation

This PR adds manufacturer column to the clients list. It shows STATION's manufacturer.

Kind Regards,
A.

Could you fix the codestyle issues pointed by Travis?

[sighook]

Done.
Sorry for the delay, I built clang locally on my current netbook to make sure I fixed it correctly :)

Can you do a force push to trigger the current CIs?
