Change GncOptionUIItem to be a pure virtual class instead of a templated one.

Browse Source 
Simplifies the design because derived classes can have whatever save UI class
they need and implement the void(void) set_ui_item_from option and
set_option_from_ui_item with whatever functions are appropriate for
the UI class. No need for callbacks or std::function members.
