Feature: updating session items after every review and sorting reviews by CurrentGrade=x (from lowest to highest)

[kirils-savinihs]

By this i mean having new reviews being added to the current session after every review so you don't have to press the "start reviewing button" every time you finish a session to get new reviews

This would be very helpful to people that have very low starting review intervals, say:
3min
10 min
and so on

This in combination with sorting the items by CurrentGrade starting with the lowest going to the highest would be cool.
