LPTJTAG:
    * Rewrite LPT JTAG driver in a native C++ DLL
    * Modify jtaglib.py to use new lptjtaglib.dll rather than lptjtaglib.py
Cleanup slow control output, more comments
IOExchange was overloaded by such large integers.. revert it to python calling shiftdata :( To fix later..
Big changes to Tester Board (Delays) Test:
    * Fixed many small issues in translation from Delphi
    * Fixed big issue with PinPoint{Rise,Fall}Time not returning any value aka doing nothing...
    * Condensed PinPoint{Rise,Fall}Time into a single function with some light wrappers around it.
    * Condensed FindStartDly and FindStartDlyPin into a single function, with FindStartDly now a light wrapper around the other..
    * Bigtime cleanup to the very ugly full-board delay scan
    * More comments ! still needs more though :(
