Big Fixation

1. Comment self._power[] to make QLineEdit work (don't konw why)
2. Set Arduino COM number to 0, if don't need Arduino
3. py2exe ,cxfreeze seems that wouldn't recongnize .egg file, so don't
find Arduino module. Solution, rename the .egg file to .zip and unzip
it.\
4. fix a bug of commenting line 194(self._shutter[channel-1] =on) by
mistake
