Arduino 1.0.2 extremely slow due to rxtxSerial.dll

I was hoping the new version of the IDE 1.0.2 would include a fix for the extreme lag some are experiencing. The fix has been developed and is well documented by eried. It involves using an alternative rxtxSerial.dll file he created. See,46977.0.html for more info.

I included the fix in,118440.0.html XD
