Add additional IBDO parameter diff options.

[jdcove2]

Currently, IBaseDataObjectDiffHelper returns all of the parameter keys and values for both IBDO's if there is any difference. This can make finding the actually differences difficult if there are a lot of parameters.

This PR does the following:

1. Add an option to display only the keys that differ for both IBDO's.
2. Add an option to display only the keys and values that differ for both IBDO's.
3. Make No. 1 the default behavior instead of the current behavior.

3. Make No. 1 the default behavior instead of the current behavior.

We're replacing the default behavior with a new behavior; is there a way to explicitly get the current behavior or is the current behavior being abandoned?

EDIT: Ah, we're making "1." the default behavior, but it's an implicit-only "option". The way you specify it is to not specify an incompatible option.

Sorry ... poorly phrased. This PR will make:

1. Default behavior be "different keys only"
2. Optional behavior, KEY_VALUE_PARAMETER_DIFF, is "different keys and values only"
3. Optional behavior, DETAILED_PARAMETER_DIFF, is the current behavior of "all keys and values".

Only minor comments, overall looks good though.
