Add dummy method MessageListItem::messageListItemDummyMessages() to allow xgettext to add possible sources to POT files. Mark a few i18n issues as FIXME as well as some messages for which the use case was not clear to me. Merged some code on multiple lines into one. Translator documentation added. Remove superfluous whiteapace.
