[1.6.3]Temporary Ork Fungus prevent planting of permanent Fungus

[zgrssd]

When a Ork Unit dies, it leaves a temporary (3 turn) Ork Fungus patch.
Meks spread that Temporary Fungus when founding a city (as the unit technically dies).
This temporary fungus prevents the planting of a permanent patch, until it has run out. And forgetting that planting is a relevant issue, given that the bonus from fungus on a Boss Tower can easily approach +4 Food.
