gsdx-hack: implement a hack for SuperMan (need CRC to enable it) 

Fix depth issue.

First issue: RT and Depth are located at the same address.
=> solution, just lookup the depth (done for any games)

Second issue: Instead to draw a X,Y rectangle, they draw a 32 pix, 4096 pix
rectangle with a FBW of 1.
=> solution, don't bother just write the depth directly

Please someone add some CRC to enable the code
