Subject: TreeView: Add rootIndex property

Its purpose is the same as QAbstractItemView::rootIndex
and allows to display only the part of the model data that
is descendant of this index.

The filesystembrowser example has been updated to only show
files reachable from the user's home directory.

[ChangeLog][TreeView] Added rootIndex property
