FO3/FNV: default DIAL override has errors

[SteveTownsend]

If the winning override DIAL has any INFOs, the INFOs in the resulting Patch mod override can have errors.

Example created using https://github.com/SteveTownsend/MergeDialogItemQuests.

The current code attempts to work around this by clearing the Responses field in the DIAL record after override. I believe I don't need these INFOs anyway - just overriding the DIAL Associated Quests list is my goal.

This is my patched DIAL for the INFO above when the INFOs are removed, which also demonstrates the INOM/INOA behaviour in xEdit that I mentioned in #676: they are auto-populated whenever >= 1 child INFOs are present on the DIAL.

It remains to be seen if this patch works for this and the other patched DIALs - I believe it will. I might need to carry forward one or more INFOs to trigger correct behaviour if the game engine behaves like xEdit. Suspect this is xEdit maybe wrongly omitting INOA if no INFOs are present on a plugin's override of a DIAL.
