Dolphin now with breeze

SUMMARY
The new highlighting for files in dolphin introduced in this commit effectively hardcodes the style of the highlight, making it unthemable for other themes like Oxygen

STEPS TO REPRODUCE
1. Update to latest dolphin
2. Highlight a file with Breeze theme
3. Change theme to Oxygen
4. Highlight the file again
5. Observe that the styling doesn't change for the highlighting

OBSERVED RESULT

The style of the highlight doesn't change, it still looks rounded and flat like the breeze style.

EXPECTED RESULT

The style should be what is expected for the Oxygen theme

ADDITIONAL INFORMATION

I have attached some images to illustrate the problem. I use PCManFM QT instead of qt as the "before" image because I can't rollback dolphin

I can confirm it's an issue, sadly there's not much we can do about it since we draw the focus effect in Dolphin and not through Breeze.
Alternative solution would be modifying Breeze itself to have this new focus style, but that can cause other problems...

So for now I have no solution, sorry.
