bookmark-properties-grid: Change to a box container and rename widget
Currently the EphyBookmarkPropertiesGrid uses a GtkGrid to layout the different widgets. But it only uses a single column, which means the grid is basically useless as a GtkBox would do the job better without requiring the different packing properties (as long as the childs are in increasing order). So this commit changes it to a GtkBox subclass and renames the widget accordingly, without including "box" in the name as it's not useful.
