Rewrite postats.sh to:

1. Not need the existence of a Makefile in order to run;
2. Not result in php warnings about uninitialised variables if any of the
   translated, fuzzy or untranslated strings are missing.

+       * es.po: msgfmt complained about a missing '\n'.
+
+       * postats.sh: rewritten. Michael's original version resulted in
+       php warnings about uninitialised variables if any of the 
+       translated, fuzzy or untranslated strings are missing (eg, because
+       there /are/ no untranslated strings).
+       Took the opportunity to make sure it does not need a Makefile to run.
