A ridiculous amount of changes

0) Merged work from the Master Branch, originally in the dictionary branch
1) Changed the test device info to an actual data set (Apple TV Menu Button)
2) Changed the “hash” property into an NSString instead of an NSInteger
3) Added code to send a test string to the Arduino (hardcoded) in the Test tab
4) Added a sendString method to the MYBLEManager
5) Added a description method to MYCommand (to be used when sendString is used)

The app should now be able to communicate with the Arduino (at least send a test)
