Suggested enhancements to Ezward's DC path_follow.py template

[TCIII]

Having been a user of ArduRover and Mission Planner I would like to suggest adding the following enhancements to Ezward's DC path_follow.py template:

1. Add a map view to the webui to be able to visualize the recorded path as other than a red line on a white background in the webui.
2. Add a throttle editing function when visualizing the recorded path on a map in the webui.
3. Be able to toggle between the map view and a camera stream in the webui.
4. Be able to toggle either the map view or the camera stream to full screen in the webui.

Comments please.
