Large change to the free file format GUI element for the user functions.

The GUI element used in the user function wizard windows has been modified to have both a 'default'
form, which is the previous design, and a 'mini' form which is now used for the user functions.
This mini form only uses 1 row, rather than the default of 6 or 8.  It is a read only text element
with a button that launches the free file format window.  The amount of space saved is huge.
Improved the text for the mini free file format GUI element.
Updated all of the user function GUI window sizes for the 'mini' free file format GUI element.

This allows much more text of the description to be displayed.
