Add starting date option for "Plays per Day" statistic

[sahinakkaya]

Description

When I started using Movary, I added every movie I could remember to my watch history with their respective watch date as accurate as possible. The movie with oldest watch date is from 2008. This makes "Plays per Day" statistic unusable for me because it is always 0. I started watching movies on a regular basis last 6 months so I would prefer "Plays per Day" statistic to be calculated since that time.

Desired Behavior

Make an option to set starting date for "Plays per Day" statistic. Only movies watched after that date should be taken into account while calculating this statistic.
