[Localization] error in polish translation

[Simon Schampijer]

Hi Jakub,

thanks for working on the translations of Sugar! In your last commit you 
introduced an error in the .po file which gives me the following error 
when building:

file=`echo pis | sed 's,.*/,,'`.gmo \
   && rm -f $file && /usr/bin/msgfmt -o $file ../../po/pis.po
file=`echo pl | sed 's,.*/,,'`.gmo \
   && rm -f $file && /usr/bin/msgfmt -o $file ../../po/pl.po
../../po/pl.po:934: a alguna de las líneas `msgid' y `msgstr' les falta 
el `\n' final
/usr/bin/msgfmt: se encontró el error fatal 1

You are missing the empty line at the end of this paragraph:

Can you fix this and commit again, please?
