Bug fix update on November 26th:

• Bug fix for NotificationCompat 24 and 25 (25.0.1). Under Android 2.2 it caused a crash when displaying the sync notification icon so it has been reverted to 23.1.1.
• Bug fix for adding iCloud accounts to sync tasks.
• Bug fix for adding an ownCloud account to sync tasks.
• Changed the default selection for "What should happen if you wait a few minutes before snoozing the reminder" to "Snooze from original time" because that's how it worked before.
• Added menu items to hide all/show all icons in the "Settings > Icons > Hide some icons" screen.
• The "Settings > Reminders" screen now shows if the "CalenGoo AlarmManager Helper" is used.
• Bug fix, when copying an event the Google Drive attachments were accidentally not copied.
• Bug fix, the color of the 5-30 minute lines in the day view could not be changed.
• Improved the speed of the "Snooze" button in notifications.
• Bug fix for "snooze until" in am/pm mode.
