The illegal white space testing for reference and value (library editor
only) fields are adequate to ensure the user cannot enter invalid white
space characters. Leading and/or trailing white space should not be an
issue for field storage in the schematic file as they are quoted. Rather
than silently removing the leading and/or trailing white space which is
frowned upon, let the user fix it.

* Refactor edit one field dialogs to use validators and transfer data to and
from window functions.
