Jeck - Card ID collisions, cache fixes, cache deleted pooling.

* mtgid now defaults to 0.
 * TextScroller will not update when empty.
 * Cache now moves WCachedResources we're finished with to a garbage pool for later use (to reduce memory fragmentation). 
 * Demo still crashes... but I'm thinking that has to do with fragmentation, not a leak?
