Add FPV web server

Add support for a PiOLED display to show useful information.

* Connect the PiOLED display over I2C, and configure the bus number.
* Change `myconfig.py` to update the bus number, and the display automatically shows useful information.
* Uses the `Adafruit_SSD1306` library.

Revert "Adding class WebFpv which is a simple web server which only serves the donkey car camera * Reduced the sleep time in the VideoAPI from 100ms to 10ms in order to achieve a less lagging web camera picture * Added the new WebFpv class with a very simple base_fpv html webserver file * Small pep-8 formatting updates in web.py and re-arranging the port variable to become a member in LocalWebController (makes more sense)"
