Support for Resource Merger in Touch UI

[pmichelotti]

Touch UI drastically changes how dialogs work in situations where components inherit from each other. These changes are not in line with the paradigm exposed by the component plugin currently. Updates should be made to allow more granular control over the merged dialogs.

Added the ability to suppress the inclusion of inherited fields and methods when extending a class or interface - this serves the use case where you are both extending a class and a sling:resourceType where resource merger enabled by the extension of the resource type is used to include the super type's dialog fields.
