Space inverts filter

- When using space on a value, all non-machting lines will be folded away
- setting g:csv_move_fold=1 will move all folded lines to the end, so
  there will be one consecutive non-folded area (there seems to be a bug
  in Vim somewhere)
Filter should work better now

Remove leading/trailing whitespace when outputing the filter
