translate string that were not, and fix a bug that make listboxes crash in some cases :

In case of binary modification, the history tab of listboxes try to display diff between binary data, but it fails because binary data can't be converted to unicode. Now a message "Binary data can't be displayed" is display instead and the listbox don't crash for this reason.
