  If add/remove sum is preceded with "*" UC25 uses multiples instead.

  ie. *5 is the same as 500%

* UC25 now checks for incorrect input. 

  ie. you can't write 10a%, or *1!

* Optional ScreenClears

* added: 
 
  (K)ill Xenolinkentry + Real File
  (M)ove Xenolinkentry + Real File
  (E)ntry move + Kill Real File

* In the letter to the user. A newline is inserted before your own
  handwritten comment ( under the Predefined comments )

* If UC.config isn't present, UC25 will work anyway, but without 
  predefined comments.

* You don't need to have 10 predefined comments, any number between
  1-10 is ok.
