Several minor improvements

- Restrict what items can be inserted into printers. They're now closer
   to brewing stands or furnaces: nothing can go in the output slot,
   only ink in the ink slot, and only paper in the paper slot.
 - Fix build.gradle using the wrong version
 - Trim the width of tables to fit when displaying on the client. Closes
   #45. Note, our solution isn't perfect, as it will wordwrap too, but
   it's adaquate for now.
