Changes in release 2010/03/29

This release focus on audio volume of alarms. It's been ignored in previous releases until some users remind me of this. Here are changes,

1. Use hardware back button to go back from filtered result.
2. Use hardware search button to do alarms filtering.
3. Force screen orientation portrait when alarm goes off.
4. Use hardware volume up/down buttons throughout OpenAlarm to adjust alarm volume. To get this, ringtones that are not alarm ringtones will not shown up on the ringtone picker. You need to use 3rd-party tools to pick up your favorite music songs as alarm ringtones or copy them into right directory in SD card. (You can find more information from my previous post)
