WebCam V1.2
Bug fix whereby previous versions took two (2) snapshots for every WEB page request.

Added ability to save to SDCard (if fitted).
Setup the SDCard with ANY 4 GPIO pins (I chose default SPI1 pins GP12,13,14,15)
and add to the 'OPTION' list:
  OPTION SDCARD GP13,GP14,GP15,GP12     <<<< change to suit
Then in the code set uSDCard=1
Copy "index.html" to "B:index.html"

I have noticed that occasionally getting a jpg file from the camera fails but
not sure why (the original code base I copied had the same problem). So I
did what they did and put an "overall" timeout, waiting for the camera. I
used the same variable/const name "SHUTTER" and set it to 10000 (10 seconds).
If you are having problems you can TRY increasing this value.
Not the ideal!
