Update vscroll latch implementation to be more in line with what Eke-Eke has observed. Revert the change to vdp_cycles_to_line because it breaks hints on line 0. H-Int timing is still a little messed up, but the previous change made things worse.

All cycle counters are now based off the master clock. This seems to have messed up Z80 interrupt timing (music in Sonic 2 is too slow for instance), but things are generally working
|
| Fri, 02 Jan 2015 13:47:34 -0800 |

In theory, the Z80 core should work on 32-bit builds now; however, I suspect there is some code that cannot deal with most of the Z80 registers not having a native register so more work will be needed
