[ROOT] Cell Network Reset

With a simple button press, issue terminal commands to reset your cellular radio.

Some ROMs are notorious for having cellular signal loss, especially the LG G3 with CM12 and other 5.x ROMs. The workaround has always been to issue `killall rild` in the terminal, but this app now does it for you with a button press.

This has gone through limited testing, so use at your own risk. Requires root access.
