TreeView: allow selecting items by touch

Only single items can be selected via an actual touchscreen, because
the keyboard modifiers are not accessible in a mouse event synthesized
from touch.  With a mouse, if the system has a touchscreen, then
selections done by consecutive clicking (with or without modifiers)
will work, whereas dragging across a consecutive range will not work
because dragging is the same as flicking.  But on systems which do
not have a touchscreen at all, the behavior is the same as before.
