Move divisor from capture scoring to good capture check and sligthly increase it.

This has several effects:
- its a speedup because for quience and probcut search the division now never happens. For main search its delayed and can be avoided if a good capture triggers a cutoff
- through the higher resolution of scores we have a more granular sorting
