Added WirelessSender class to libscout
WirelessSender will hold some metadata like packet destination, pan, andchannel, and will publish a WirelessPacket (also, addedmesssages/WirelessPacket.msg) to /wireless/sendSo far, lacks proper documentation and static functions similarly named...
Added the ROS stack with the libscout, motors, and sonar packages to the reposititory, and associated files. There are probably still things missing. Libscout won't run properly, but it and motors will compile. Sonar is probably broken, but nothing depends on it yet, so this shouldn't be an issue.
