Applet !Unique
--------------

Inserts unique number with prefix at the caret.

Adds 'Unique number' option to the Applets menu, and defines 'unique' button
for the button bar (disabled).

Click on 'Unique number' to insert a unique number at caret.

The sub-menu provides the following options.

'Start'             Restart numbering at the number specified.
'Prefix'            Specify a prefix for the number.
'Save in document'  If this option is selected, the number and prefix are 
                    retained in the current document

Prefix and number are stored in the file !Unique.uniquenumb and are
therefore retained between sessions.
