Blunders should be split

[benheideveld]

Is your feature request related to a problem? Please describe.
I am always frustrated when Blunders are not differentiated between losing blunders and missed winners.

Describe the solution you'd like
For people that think like me, there should be a toggle in the settings that gives you the option to spit blunders into two kinds of blunders. Losing blunders and missed winning moves.
