Upgrading from previous versions of Win-I2CNTDLL

1. Why upgrade?
   - Win-I2CNTDLL v4.x adds support for Windows XP.  
     Win-I2CNTDLL V3.2 and earlier versions did not support Windows XP.
   - Three new functions were added to Win-I2CNTDLL:
      -  SetWaitTime - allows the user to increase the wait/hold times for slow I²C peripherals
      -  I2C10_WriteArray (10-bit addressing) 
      -  I2C10_ReadArray  (10-bit addressing)
