Update: Finish updating fss_write.

Update: Finish updating fss_write.

Remove the unused files.
Simplify the processing callbacks using ternary operators.
Resolve the void_setting to the specific setting for easier to read code at the cost of allocation more memory (1 memory address variable per function).
Implement the ignore functionality.
Make sure the multiple Content is supported where appropriate.
The flags must not be reset at the start of the setting load so that main.c programs can pre-fill the flags.
Add all of the supported write program setting files.
Other miscellaneous changes and fixes.

The pipe data is lacking and will need future reviews and probably will need fixes.
The original fss_*_write pipe data is also lacking so I feel that it is fine to leave it alone for now to be addressed later on.
