Morse Code Flasher

May 23, 2016

- can now flash with the phone's camera flashlight;
- the history of messages is now stored in the preferences (is no longer destoryed when you close the app);
- messages don't get duplicated in the history. The most recent message is on top of the list;
- replaced the "Repeat" button with the "Loop" button, which will loop the current message instead of transmitting it once;
