Better vertical scrollbar handling; unfocus entry on search
For checklists, there might be a vertical scrollbar when checklist
items get too long. When switching from one checklist to another,
this vertical scrollbar is not removed. Fix this by calling the
columns_autosize function of GtkTreeView after a node change.
Unfocus the search_entry widget when search is done, so the virtual
keyboard gets hidden on N800 and devices with virtual keyboard.
