Update: Have iki_write use form-feed rather than end of line character for pipe input.

The IKI specification allows for just about any character inside the content, including newlines.
Given that newlines are far more common than form-feed characters, switch to form-feed.
The form-feed character is chosen because there is a standard escape sequence that can easily be passed to commands like echo.
For example: echo -en "a\fb" | iki_write
