*POSSIBLY DESTABLIZING CHANGE, PLS PING ME IF YOU SEE ISSUES*

Turned on the threaded card fetching code for win/linux.  PSP runs unthreaded.   There's an easy toggle for switching which mode the app runs in: check out WResourceManager's constructor.

To fully appreciate the difference, try going into the deck editor without these changes, and use the arrow keys to navigate around (esp. up/down, as it loads 7 cards at a time).  Then try again with these mods, you'll see the cards flicker briefly to the back card image and then load as they scroll onto the screen.
