small tweaks to the prev/next buttons in the minibar:

- reduce their width of the 10%
- reduce their icon size, so they don't take 40px of height
- remove the custom hover code, Qt::WA_Hover does that for us
- make use of an already-there function to cut a pair of lines of code (yay for easiness!)
