i18n: build_translation, i18n/->po/

mmaker · mmaker · commit c7ab1dd10b03 · 2010-07-19T09:00:02.000+02:00
".po" files moved to directory "po/", renamed using the following template:
"lng_LNG.po". File "setup.py" properly configured to build .mo files, with
"build_translation" option. bPython's main() functions (cli.py, gtk_.py,
urwid.py) properly modified in order to use gettext.
