change start.sh to use SH instead of BASH

[paulwratt]

(I have other PR's and since this is a one liner ..) The shell startup line in ~/CommanderPi/src/start.sh should be change from:

#!/bin/bash
sudo python3 ${HOME}/CommanderPi/src/main.py ${HOME}> log.txt

to:

#!/bin/sh
sudo python3 ${HOME}/CommanderPi/src/main.py ${HOME}> log.txt

This way it will work on any setup, not just ones that have bash installed.

NOTE: the same should be done with ~/CommanderPi/install.shtoo, as there is nothing BASH specific in that file either. SH is always preferable of BASH for scripts, unless there an explicit need for BASH specific command usage (which there are always known workarounds for anyway)

Alright, pushed.
