ConfigBlock: remove groupName, change noneAction, and duplicateAction

The groupName variable was changed to blockName and set from a
set/get function.

Add instanceName to identify specific instances when there is a
desire to set the value of an option in an arbitrary location and
there is more than one instance of a block.

Removed code to potentially throw an error if an option was
set more than once.

Instead of haing the user say "I am setting this option to None
and it is okay," the noneAction variable can be set when adding
an option. If the author of a class determines that an option
can be set to None, then they can set this for that option.
