The font name is Arial not 'Ariel'.
Hmm trying to do something good here. Stopped at str object is not callable.
No support for i18n at the character class right now.
Extension changed to .py.
Character class working for now. We need to provide some usefull messages.
More fields added for verification. New feedback messages.
Autoload packed into run verification.
Add Monster and Char now uses add_char and Character objects.
Some PEP-8 Fixes. Simplified attributes at char buttons
Name repeated is now verified and a error message is now presented.
self.chars will receive character objects.

Will be usefull later, to sort and do other operations.
New sort method added!!!

The old method 'ordenar' was deleted from the code.
Docstring of the method sort updated.
init_order attr at the Character class is not needed at all.
saved attr is not needed at the Character class.

The method clean_by_char_type is not implemented and should an NotImplementedError if used.
The new change_initiave methods is in place of the old altinit method.
The software now uses the new functions open and save, and have a reserved method to associate Character instances and listbox selections.
Enough for now. Some TODO's added and tomorrow we shall see what happens.
Now the INT fields of a Character are converted for INT type.
Finally the shift_turn method works.

A try was needed because an inexistent registry that queued by 'get' returns '' :S
