Added 102! successfully tested cards.

After weeks of hard work, I can proudly present you this huge package of cards, based only on already existing card code elements.

Some examples and important notes:

- Cards that get buried if you don't fulfill a condition
1. when they enter the battlefield (Hidden Horror[WEL]; Mercenary Knight, Thundering Wurm [both POR])
2. during your upkeep (Endless Wurm[USG]).

- Cards that allow to draw a card, then discard a card when entering the battlefield or damaging an opponent (Owl Familiar[POR], Looter il-Kor[TSP]).

IMPORTANT NOTE: Those cards work only correctly because the draw effect resolves before the discard effect. 
Instants and Sorceries with such effects or permanents that have an activation cost for drawing, then discarding a card won't work because the two effects don't trigger in the correct order.

- Land cycle from Visions and Planeshift (both very puzzling, but working perfectly!)


I also updated World enchantments (tested & working, see rules for them in Gatherer!)

Several card fixes.


If you have any questions, post them! ;)
