Minor changes throughout the app

I wanted to give my shot at improving this app. I've worked with Android quite a bit in the past and have put my own app in the store; now I want to help out here! Hopefully this is a good start.

On the main screen I made the settings menu Android 3.0 compliant. The "more" option is gone and the options flow onto the action bar if there is room. Unfortunately, the icons that were put into place in the settings menu won't render anymore because it is in Android 3.0. I'm guessing there was a workaround that you guys put into place to have them appear. It's better to not show icons than to force the user to tap "more" to show the real menu.

I fixed a quote in quotes.txt that was displaying a mystery character.

Lastly, I removed the "Home" button from the Gym Activity. No other activity has a home button so it was inconsistent. The back button should be used on the phone instead.

That's all! Hopefully I will have more time to contribute in the future. I hope I didn't completely mess up the workflow of everyone here.
