(from 'original to 'ver1).
* The client gets the list of extra fields from the server (when the
dialog is used for the first time), the full-name, ID, and email
fields are now part of this description which is in the server
configuration file
* The network protocol has a generic initial part when clients set
arbitrary key/values that are later used for actual actions
* In the submission dialog, there is a checkbox that makes it retrieve
the submitted work instead of sending a new one. The retrieved
contents will pop up in a new DrScheme frame. The file that is
retrieved is the newest WXME file that is found in the student's
main submission directory.
* The hack of returning a list from the checker is not needed now --
it is possible to send text messages that are displayed on the
handin dialog and it is also possible to send message-boxes and get
the result that the client returns after getting the user response.
This is a much better generalization of the single final popup that
was enabled by the list hack.
* When registering, a second password for verification is required.
* It is now possible to edit any information field, with a
configuration entry that locks by default any such changes.
* It is now possible to standard Unix encrypted passwords instead of
MD5 hashes -- so a "users.ss" can be made from a plain /etc/passwd
file.
