Mover network monitor into rep. Edited it to handle eth0, then wlan1 and then wlan0

-NetworkMonitor needs testing using wlans...

Also added git pull to sudo crontab (bypassing CameraUpdate.py for now)

-must check if full updates are passed through and can then be run... This means that each Pi will run just the crontab referencing the
 python scripts that are downloaded through the rep...
