Moving to generics for timing parameters
Using less-than rather than less-or-equal
Doing dispOn check in top_level
Switch to concurrent assignment of hCount_next & vCount_next
Switch to using pixClk to clock registers in vga_sync module
Added synchronous reset to vga_sync module
Generate pixClk using DLL
Add top_level comments
Readability fixes, comments, hCount_next simplification
More comments, correct hSync & vSync polarity
Removed template junk and arranged 640x480@60 and 640x512@50 timings in top_level
Now generates a test-card of eight colour-bars
