CI_Input tweaks
- Make get_post(), post_get() and server()'s parameter mandatory.
- Change default value of parameter to NULL for cookie(), input_stream() and _fetch_from_array()
(for consistency with get(), post()).
- Delegate Array-vs-single and parameter detection to _fetch_from_array() to overall simplify the code.
