New version: Memory

Hello boys and girls;

A new update for House Of Cards and this time I added Memory. 
Well, it's played with cards, there is a solitaire version of it AND it was easy to implement, so what the heck, let's just implement it, eh?

Next stop is "Soloslag". A solitaire game of my own design.

(One notice. If anybody gets the "Banking error" when playing Memory with setup where the numbers of rows do not match with the numbers of columns, that bug has been fixed already, and is being uploaded as we speak, so just reinstall and you should no longer suffer).
