OK, done.
Beware that it does NOT make any sanity check on the puzzle as you save 
it - so if you have specified some values that do not permit any 
possible completion - it gets saved. Even if you have already got to a 
blocking point (with "?s showing), it gets saved.
The file format is the same as used for loading - so every square is 
either a known, fixed, single digit - or is shown as "x". So if you are 
working through a puzzle, and have reduced the number of possible values 
in other squares - possibly down to a single remaining value - they are 
nevertheless all shown as "x". It is only those squares that you have 
defined that get their digit in the file.

btw - it's still faster to edit the file by hand :-)   
Depends on whether your a "command line, text editor" user or a GUI guy :-)

Also fixed some typos in Help, removed the annoying "put ... msg", and 
added version number (1.1)
Didn't manage reproduce the "square goes blank" problem yet.
