Added file WifiDirectBroadcastReceiver, helper class for WifiP2p
functions.  Put in wifi p2p tests in the SplashScreen Activity, this Wifi
p2p code has been outlined in comments so that it may easily be
transferred to MainActivity where it belongs. It is currently in
splashscreenactivity for easy debugging.  Also made changes to
AndroidManifest.xml, wrote in permissions for Wifi and Network access.
