Find/replace tool bar wasn't usable in very small width editors.

E.g. in split editors with small main window. We now have line edits
with a minimum size and use a flow layout for the replace buttons (which
will reduce width when necessary by laying out vertically).

Flow layout is taken from the Qt examples.
