changing so that for folder pretty names that are I18N messages containing variables we don't store the message key anymore, but rather the en_US message (should be improved to be the locale of the community). This applies to messages of type "%user_name%'s Public Files" and "%community_names%'s Public Files". The problem with those vars is that file-storage would need to have a way to lookup community_name when displaying a folder name. Allowing folders with messages with no embedded vars to still have their pretty names be message keys in the db. That way we can have Assignments, Exams, Handouts etc. be multilingual.
