Development Build v0.4.0

In this release, I've made several fixes regarding the UI. I've also added the other difficulties for the math problem to which I will go into more detail here.

DIFFICULTY CHANGES:
-Easy: 0-10 (Addition/Subtraction)
-Medium: 0-100 (Addition/Subtraction)
-Hard:
------If multiplication, then 0-12.
------If division, then the first value is 10-50 and the second value has to be between 2 and 9 and it has to be a multiple of the first value. If it can't find a number between 2 and 9 that's a multiple of the first value, then it will generate a new first value.

UI FIXES:
-I've made the UI more adaptable to various different environments. I had to do a bit more tinkering with the math problem activity but I think I got it all down.
-You should now be able to rotate your device to landscape mode and still have DJ Alarm work perfectly fine.

ANNOUNCEMENTS:
-I'd also like to mention that I have a Trello board that I'm using to keep track of development: https://trello.com/b/OOyJXCBC/dj-alarm
-The app is nearing completion. I've gotten to a point where now I just need to do some fine tuning and polishing. After that, it's ready for production on Google Play Store.

Development Build v0.3.0

In this build, I've fixed some major issues with the audio.
-Fixed an issue where the audio would come out on different channels, sometimes random.
-Fixed an issue where the app would crash when you would try to set a tone that wasn't distinctly an alarm tone
-Made improvements regarding overall performance

Development Build v0.2.0

These are the patch notes from the previous build and the overall changes that were made since then:
-Changed the Alarm tone type over to Alarm rather than ringtone
-Added more functions to ensure persistence
-Made several changes regarding overall performance

After this, I will continue to work on persistence and making absolutely sure the alarm goes off, as that is crucial. In the near future, I plan to include 2 other difficulties with the math problem preceding release.
