Title: Pathbar single step scroling fix

This fixes some issues with pathbar scrolling and adds some documentation and a bit refactoring for hopefully better understandable code.

Unpatched:
* Pathbar scrolling in sub-folder direction always jumps to leftmost button
* Pathbar scrolling in parent direction can skip folders because bug in space calculation.
