* Give Shyde and Sylph unwalkable flight
With the same unwalkable terrain movement and defense as the Quenoth versions of these units. Makes them behave as true flying/floating units as their wings, movetype name and other statistics suggest, while opening up interesting game play possibilities.
* revise I-type terrain codes so they can be filtered with wildcard
* update the few MP maps using these I-type codes
* update the few campaigm maps using these I-type codes
* DiD S8: Handle situations where factions have not yet appeared (resolves#7005).
* Convert 'arrived' flags to booleans.
* DiD S8: po hint to clarify 'Dela's men'.
* Accommodate feedback by getting rid of all the new work and just removing any reference to paladins or Dela altogether. Conversion of flag to boolean remains, however.

It does the same thing as PLACE_IMAGE except the created item may
use the same submerge code as units. If not placed on water there
will be no submersion effect. If placed on water it will be submerged
to the same level a unit would be submerged to. In general physical
items placed into water should use this, whereas items placed on top
of water should use PLACE_IMAGE.
The new macro has been applied to the merfolk cages in the Bay of Pearls
scenario in HttT.
