settings: Show more hardware information about the device [1/3]

pulls the following build.prop settings and displays them

ro.device.chipset=value
ro.device.cpu_info=value
re.device.gpu=value
ro.device.front_cam=value
ro.device.rear_cam=value
ro.device.screen_res=value

PS9: rename cpu to cpu_type
     add cpu info

PS10: add device codename info (I think it may be useful)
