Progress: FSS development and other changes.

Work on the FSS Basic and FSS Extended write functions, changing the design strategy.

The FSS Extended Write program needs additional consideration for how to handle multiple content (which may entail changing the logic of FSS Basic Write accordingly as well).
The Basic List and Extended List are currently not worked on but will be.

Use "quote" instead of "quoted".
After review, this makes more sense to me overall.

Fixes of other observed issues, such as missing "_t" in some macros.

Update the FSS documentation, focusing on the FSS Basic and possibly FSS Extended.
