Added call from CameraUpdate.py to update.sh that makes pull request to git server

Still to do:

-call to update.sh not working
-add db col for update requested (currently always)
-add updatecamera to sudo crontab (where everything is now)
-update wifi reconnect to check if lan is in, and if wlan1 is available to connect to that...
-move wifi reconnect to git folder...
-clean up pi...
