Polish Plural-forms

[Eliovir]

Seen at http://bazaar.launchpad.net/~e17-users/enlightenment/l10n-import/view/head:/desktop/pl.po

"Plural-Forms: nplurals=2; plural=(n!=1);\n"

whereas it should be

nplurals=3; plural=(n==1 ? 0 : n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2);

according to http://docs.translatehouse.org/projects/localization-guide/en/latest/l10n/pluralforms.html

So, update-e17-l10n-from-desktop.py must be enhanced.
