Suppress write-back for hierarchical keywords

[Vincent9756]

Optionally suppress write-back for hierarchical keywords, and all the features and functionality which depends on this until such a time as the industry in general defines and adopts that standard. (More than just one single software application).

To be clear, with this option disabled:

- I would only be allowed to use flat keywords.

- IMatch would write them out in the same way it did in version 3 which appears to be compatible with almost all other software apps that read/write keyword tags.

The main reason being is that I have 300,000 images and I don't want to update them each time Adobe chooses to disregard those standards or just simply changes their mind.
