base-icon: Add an option to not show the label

Browse Source 
Currently there is a serious problem with ellipsization in various
parts of the overview. While wrapping the label or giving it more
space may be appropriate approaches for the application view, neither
works very well for the dash - possibly the best option there is to
not show the label at all.
So add a constructor parameter to BaseIcon to allow hiding the
label.
