Improve diary input interface
Improve Diary input ui
Now it can send a notification when a user hasn't input his/her activity
for a while
Best diary input interface ever
Notification for no input for long time
By default, next activity's start time is this activity's end time
Add SimpleReadDiaryActivity for temporary uses
Default start time will now be set to the end time for the last event
Time between two notification increases from 120 to 240 mins
