Created the user_functions.uf_translation_table list.

The elements of this list are the names of user functions before and after a renaming. The list is
provided for backwards compatibility for relax scripts, though it is not used yet.
.....

Hack in the script UI for handling missing user functions due to it being renamed.

This script UI requires a different solution as the prompt UI. The script is executed via the runpy
Python module and there appears to be no clean way of catching each command before it is executed.
So instead, prior to executing the script, the contents of the script are read and old user
functions are searched for using re.search(). The old user function name has "(" appended to it in
the search so that it is sure that it is a user function call. And the old function must have a
space or newline character preceding it.

The prompt UI now uses the user_functions.uf_translation_table dictionary.

The modified runcode() function will now check if the command typed by the user is a function or
method call and then will raise a RelaxError if the command name is in the
user_functions.uf_translation_table dictionary, telling the user that the user function has been
renamed to the new name in the translation table.

This appears to have no effect in the script UI however.

Converted the user_functions.uf_translation_table object to a dictionary.

This is for faster access which does not require looping.
