keepUP script to cron tab

- prerequsite: sudo apt-get wvdial aiccu glib-networking-common libqmi - first if IPV4 dose not work start's Huawei E398 reset and setup - if aiccu ipv6 tunnel not respond restart's IPV%

bug's: dose not detect problem's in DNS and BIND, DNS and BIND need's

own restart and cheking as weel !
