I'll collect some missing translation keys here, they will be added over time.
Keys which are (assumely) only relevant for Shibboleth are tagged as such.
EnterFilename - as displayed when you failed to enter a filename in the "Save Game" dialog but just clicked on "Save"
build Self (Shibboleth) - as found on the description of a building which is just executing this command
wall (Shibboleth) - as found on the pop-up info for the "Build Wall" command
