Subject: [PATCH] Forward Declaration of OnRandomMACAddress added.

Added function to create random MAC

...added headers needed for CreateRandMAC

Defined function to create a random MAC

Added in option to randomize MAC address

Changed uint_16 to u16 from CommonTypes.h

Fixed case sensitivity. Woo!

QT -= gui caused <QTGui/QImage> to not be found

undo unnecessary change

undo the undo

removed random option, fixed spacing

removed forward declaration

Changed default mac to random one

Added in several STL includes: iostream, sstream.
CreateRandMAC is now only used for initial runs, no more random option.

Removed unneeded headers

Moved ctime and cstdlib to the cpp file

Added in random MAC function call

Update Config.cpp

Revert "undo the undo"

This reverts commit e21852961806727230dca31ceb5193ee2f298c7b.
