Fix executable bits and add camera name to 4-seasons notifications

- chmod +x all *.sh and *.py in install.sh so permissions survive git checkouts
- Fix daily_sunrise_video.sh and Python scripts missing executable bit
- Add [CAM_NAME] prefix to all 4-seasons.sh notify.sh calls so multi-camera
  setups show which camera each daily clip came from
- Include camera name in output filename: YYYY-MM-DD_<cam>_MvtN-DayXofY-final.mp4
