[Feature Request] Point-Loss Graph

[pscheid92]

Context

I use the point-loss value to identify blunders and further review my games.
I think having a graph of point loss would make finding hot spots easier.

Solution

Add a point-loss graph similar to the score graph.

Implementation

I implemented this (see screenshot below). Tell me, if this is even interesting for Katrain. If so, I can open a pull request.

Doesn't the score graph give you this already?
Could plot 'for current player' to not oscillate, in that case could be more useful perhaps?

Yeah, well, partially. It would be a convenience function to make it easier to find places where you lost more than 10 pts, for instance, because these are shown as strong deviations from the zero baseline.

But as you rightly said, I can also just look for big jumps in the score graph.

I have no strong opinion here :)

Regarding this:

Did you imagine something like this?

No, instead of "W+30" "B+30" just "-30" from the perspective of the current player. A series of identical mistakes would show as a constant ish value, rather than oscillations.
If you agree that looks nice, feel free to proceed with a PR.
