UI: Use responive layout for upper bar in file browser

The upper bar (containing file path, navigation and display buttons) may
now be split into two rows as horizontal space is reduced.
The first row contains the navigation related buttons, the lower one the
filter and display related ones.

Mainly solves the issue where the file path and search buttons became
barely usable in tight layouts, but generally makes things better for
such cases.
