Fix dynamic allocation of IconButton instances

Browse Source 
Previously, IconButton instances to be added to button boxes were
allocated with new, but never freed with delete.

unique_ptr makes sure the buttons will be freed along with the button
box that owns them, or when code calls ButtonBox::clear.

The destructor of ButtonBox has been made redundant by this change, so
it's gone.
