custom_safe_eval : add pprint function

[Maurine Antonis]

As print function is used here :

odoo_utils/custom_safe_eval/tools/safe_eval.py

Line 7 in e4aa24f

 _BUILTINS['print'] = print 

maybe add the pprint function.

Like said in Python docs,pprint is just a function that "pretty-print"s a variable or a message.
The pprint is really useful when using dictionaries.
