Updated NO translation - Some questions in dscr.

Did X more lines.

I'm afraid to change stuff that's not in quotes, so I'm unsure whether or not I should be changing line like these:

      browse_all_categories: Browse all categories

      view_latest_topics: view latest topics
      suggest_create_topic: Why not create a topic?
      jump_reply_up: jump to earlier reply
      jump_reply_down: jump to later reply

or these:

      progress:
        title: topic progress
        jump_top: jump to first post
        jump_bottom: jump to last post
        total: total posts
        current: current post
