Improved colors for better visibility.

Made a little more room around the Sets label, and did some other minor visual changes to better support smaller iPads.

1. The Buddy app is now responsive to the orientation of your iPad (since it can be difficult mounting the iPad to a padded pole in landscape mode...). 2. The Buddy app can be used in portrait mode on an iPhone for bench personnel (hopefully to eliminate out of rotation and alignment issues). *Note that it is a scroll view, so if you have a match with challenges, you may have to scroll to see the counts!! 3. The Buddy has a power indicator in the bottom left corner that shows when the iPad is below 20%. 4. The sets won box is responsive to indicate the winner at the end of the match.

This version of the VolleyWrite Buddy displays timeout, challenge and sub counts differently when they are at their maximum. Using a red background with white text indicates the situation much more clearly. When the sub count is within 4 of the maximum, the background is gray as a warning. The final change is indicating set point with a yellow background on the appropriate team's score, as shown in the screenshots.
