Summary: Player SVN trunk: small improvements for camera drivers

Initial Comment:
This patch provides some changes for imgcmp and cameracompress drivers:
1. imgcmp - image difference threshold is now given as double value in range 0.0 - 1.0 instead of integer value between 0% - 100%; experience showed that integer value is not precise enough for bigger images (1% of 640x480 image is a huge area when camera is far enough from observed workspace)
2. cameracompress - missing documentation regarding configuration file options added
3. cameracompress - new option: check_timestamps added; cameracompress is used mostly to prevent bigger throughput on tcp networking; avoiding repeating images (with the same timestamp) can additionally help to prevent some overhead information to be passed through the network. This option is off by default as it should be used only with camera image drivers that set timestamp meaningfully.
