Comment 2 for bug 579467

I found a useful tool to sync translations:
http://propertysync.appspot.com/synchronize.htm

It's a mess with non-latin characters but still useful to find missing properties.

Here's the result for values-bg:

<!-- Missing prefs -->
<string name="no"></string>
<string name="reset_trip_statistics"></string>
<string name="uk_postcode_not_recognised_title"></string>
<string name="namefinder_service_label"></string>
<string name="aver_trip_speed_label"></string>
<string name="not_available_string"></string>
<string name="yes"></string>
<string name="close_statistics_view"></string>
<string name="trip_distance_label"></string>
<string name="trip_duration_label"></string>
<string name="current_speed_label"></string>
<string name="uk_postcode_not_recognised"></string>
<string name="menu_show_trip_stats"></string>
