Order of lines in symbol definition matters!

The order of the lines in a symbol definition matters where the symbol is displayable when referenced and this should not be the case.

This symbol is good and displays:

  symbol
    name "S"
    type svg
    image '/u/data/tiger2011-maps/etc/svg/hwy/S-blank.svg'
  end

This symbol does not generate an error but it will not display the symbol when it is later referenced for use:

  symbol
    name "S"
    image '/u/data/tiger2011-maps/etc/svg/hwy/S-blank.svg'
    type svg
  end

In general, in the mapfile the order of the object attributes does not matter. In fact the ONLY case I am aware of is the fact LAYER TYPE must be defined before a FEATURE object is defined. We should avoid creating more cases like this.
