Qsearch simplification. (#1828)
Don't do an extra TT update in case of a fail-high,
but simply break off the moves loop and let the TT update
at the end of qsearch do this job.
Same workflow/logic as in our main search function now.
Tested for no regression to be on the safe side.

Reintroduce tropism to kingdanger
Tropism in kingdanger was simplified away in this pull request #1821.
This patch reintroduces tropism in kingdanger with using quadratic scaling.

How do we continue from there?
I've recently tried to introduce tropism difference term in kingdanger which
passed STC 6 times but failed LTC all the time. Maybe using quadratic scaling
for it will also be helpful.

Remove the tropism term from kingDanger
A recent LTC tuning session by @candirufish showed this term decreasing significantly. It appears that it can be removed altogether without significant Elo loss.
I also thank @GuardianRM, whose attempt to remove tropism from king danger inspired this one.
After this PR is merged, my next step will be to attempt to tune the coefficients of this new, simplified kingDanger calculation.
