  DESCRIPTION
  Allows a user to set the input/s and textarea field width, height, fontSize, fontFace.
  
  Firefox & IE7 users can access the preference settings via right-clicking
    the IE7Pro/Greasemonkey icon and choosing a setting from "User Script Commands"
    
  ** Opera users have to edit the script to change preference settings. **
  
  Firefox users also have the option of changing preferences via...
    about:config
      width        - width of inputs and textarea content
      height       - height of textarea content
      font_size  - size of font in inputs and textarea content
      font_face  - font family in inputs and textarea content
*/

/** changelog
2007-10-27
  Fixed:
    *blush*  Missing the IE store setting for FONT_FACE - fixed!
    *blush**AGAIN!!* meant to move default vars to private - done.
  Tied myself in knots checking for valid returns - fixed (hey, I'm a js newbie!!)
  For inputs in "Post a new topic" only expand width of "Poll question"
  New:
  Added rudimentary error checking for menu prompts
2007-10-26
  New:
    Think it is now worthy of a version 1.0 release.
    as it's been expanded upon,
    and is now cross-browser - Firefox, Opera, IE7
2007-05-23
  New:
    script "phpBB Expand Posting Form" by Glenn Carr - userscripts.org
