Add editing functionality to the TBODeveloperOverlayNSUserDefaultsDatasource

[brototyp]

I guess there are situations where I would want to edit values in the NSUserDefaults.

Points to consider:

• Should this be a functionality of the default TBODeveloperOverlayNSUserDefaultsDatasource or would the best way to subclass it and add the editing functionality?
• If implemented in the TBODeveloperOverlayNSUserDefaultsDatasource, how would we configure which keys are there to edit?

What if we make all or none keys editable by initializing the datasource with an "isEditable" parameter?

Hm. I guess that is quite a black-and-white solution. I can imagine situations where you only want to be able to edit certain values.

What do you think of this solution:

• per default the TBODeveloperOverlayNSUserDefaultsDatasource doesn't allow editing any fields
• one can implement a subclass and enable editing TBODeveloperOverlayNSUserDefaultsDatasource via -isEditableForIndexPath: for only certain values
• – didChangeValue:atIndexPath: is already implemented in the TBODeveloperOverlayNSUserDefaultsDatasource

I like that idea.
