he.po in branch contains a number of translations where the translation is identical with the original text (e.g. for encoding names) which look suspicios to me. Therefore I did not want to merge these and leave the decision to the translator. No information is lost, since these "translations" can easily be recreated from the original texts by copy-paste.
