A few minor fixes for layout performance, and removing a few extra
comments/blank lines.
Drop 1 of UI changes:
-Add a layout for when the app is in landscape mode. This will better
accommodate changes in the future (and just looks better on smaller
devices (hopefully)
-Removed the Save option and added to options menu (it was no longer
visible in the new landscape mode on smaller devices anyway).
UI Changes Drop 2:
-Switch to using a grid view to display the chords/measures (which I am
currently calling "song blocks")
-Clean up layouts to accommodate this grid view better (for example,
move or remove scroll views so I don't have a grid view inside of a
scroll view).

Implement basic part switching (right now it is hard coded with Verse,
Chorus, and Verse + Chorus). Need to generalize this for when I refactor
songs.
UI Changes Drop 3

More tweaks to display
-Apply some custom drawing to the grid view items (to sort of emulate
something like lead sheet notation)
-Remove most of content from display text
-Other small tweaks
Minor update to song generator jar
Remove MediaPlayer (since FluidDroid is handling audio now)

Also clean up extra comments
Remove extra imports after removing Media Player
Allow the synth to continue playing on app restart:

Use the newly added FluidDroidSynthFragment to persist the synth and its
state on app restart (such as when rotating the screen). Also, since the
synth now handles the audio focus, remove that code from here.

Also, attempt to make sure the support library is in synch with the one
in the FluidDroid library

NOTE TO FUTURE BRYAN: I removed a lot of commented out code that has
been just sitting around for a long time. If you decide you actually
wanted any of that, you can find it here.
Have the main activity implement the new SongFinishedListener provided
in the FluidDroidSynth class

We implement the callback function to reset the UI state when the song
has finished playing (either by running out of notes to play or by being
stopped by the user)

Also made small change to the grid view layout to make it look a litlle
better.
Update song gernerator library

Includes:
-adding proper sharp/flat symbols
-adding new scales
Added code to scroll gridview to top when setting a new song (for some
reason you have to post a runnable to gt it to work correctly...)

Also updated song gen lib
Several changes in the UI

-Show prompt when no song has been generated yet
-Hide some extra UI elements
-Playing around with the control appearances a bit (not very happy with
it yet, though)
