Electronic poetry - round 21 : special planet features

I have added the possibility to have special features, such a pyramids, ship wrecks...

 A lost shipwreck lurks among cold swamps
 A marvelous ruins shines under scortching seas
 A insignifiant cracks lurks under humid marsh
carnivorous plant thrive on Vega second
whales thrive the moon
carnivorous plant survive on Sol prime's cold marsh
 A hidden ruins is among water
On gamma-Washingbia, huge oasis spread along the rocks
 A great caves is lost under scortching montains
On old-Vega IV, huge bog spread along the marshes

It is a nice touch. However, many sentences are too rich, and some bits of texts really don't match. Some cleanup is required !
