2.0.2

This version add the implement for "speed limit" function which has been forgotten.
The rpm displayed in the monitor will no longer be 0 if you sleep and wake the PC.
Linux version is now available, but the .so files maybe be not complete, so you have to fix the libraries by youself.
For autostart on Linux, I choose to chown the executable file to root and set uid so it can always run in root privilege. But this is not a safe method, so you'd better find another way youself.
