Update: Use f_console_parameters_t as a pointer and document fll_program_parameter_process_context_standard().

Make the use of `f_console_parameters_t` as a pointer for consistency purposes.

Some programs did this whereas other programs repeatedly called `main->program.parameters`.
This should no longer be the case.

The documentation comments should be referencing `fll_program_parameter_process_context_standard()` and now do.
