* Fixed the textarea_set/get_cursor_position methods to use the method interface as specified in docs.textarea.  I wasn't returning values in R4 as it showed in the document, I am now.  The fetching of the cursor position (in both the get and set calls) doesn't appear to work (always returns 0) with what appears to be the correct code to achieve this.  The fixing of this is left as an exercise for the bored and very brave person...textarea internals are "interesting".

 * Added some description of the methods into docs.textarea
