Adding activities in retrospect is very hard
Created by: gsobczyk
Update edit_activity.py to components in the form be aware of selected date
For activity in cmdline: some activity
(without date and time)
- checked incrementing and decrementing day
- checked date picker
- checked date picker set to one date and cmdline on another date (cmdline has higher priority)
This fixes #627 Adding activities in retrospect is very hard.
