[Gramps-devel] minor python style issue: use logging .warning not .warn

[Vassilii K. <vas...@ta...>]

Answering to a question I've encountered hidden in bug# 7172 additional 
information:

 > Otherwise, a python issue: should we use LOG.warn or LOG.warning when 
we want to print a warning?

Since in Python3 (see http://docs.python.org/3/library/logging.html ) 
the "warn" syntax is deprecated, I think we should be using "warning" 
not "warn" in the new code as of gramps40.
