ibeacon 1.0.1 (new formula)

Add formula for [Radius Networks iBeacon CLI](https://github.com/RadiusNetworks/ibeacon-cli). A utility for scanning and transmitting iBeacon profiles over Bluetooth 4.0.

This would address RadiusNetworks/ibeacon-cli#4
Can this test be modified to do something more substantial then e.g. `--version` or `--help`? See `cmake.rb` for an example of a formula with a good test. Thanks!
