Chinese Lunar Calendar Alarm

Invalid date

- Fixed Chinese Date Conversion Calculation
- Fixed Some Country Timezone Incorrect Conversion (e.g Singapore & Malaysia)
- Add Application Widget

*Disclaimer Note : For Android OREO Users : Android Oreo has limit the access of background service, sometimes the alarm is killed and will not work. I Still finding way to make sure the alarm will ring on time. For older android version will not have this issue.
