Misc

+ Splitting functions out of main into own files
+ Can now scan events for a pattern
  - So I can look for sequences of events that have a bit got 1 -> 0
  - Next step turning them into hsync durations
  - and hsync to hsync to hysnc durations (line time)
Loads of changes

+ VCD scan now works, reports hysnc and hline durations
+ tells me how far I'm off target
+ And I'm no longer off target
+ Vsync next
Cp from pgm to ram util
Fixed cycle length copper list runner
