Add a itemMaxLines attr to NavigationView and propagate it down to the internal CheckedTextView.
Also, make a slight change to design_navigation_item.xml layout to accommodate multiple lines of text. Without the layout change, the layout_height of the item is set to "?attr/listPreferredItemHeightSmall" so it can't contain an arbitrary number of lines. It can also chop lines in the middle.
To fix this, we change layout_height to "wrap_content" and add a minHeight attribute set to "?attr/listPreferredItemHeightSmall". This results in the same behavior for single line items but expands appropriately to contain items with multiple rows.
