Create setup script

[CuriousJames]

Create a scrip that 'installs' DIYAC onto the Pi - i.e. setups up the perpetual running of reader.py and cron job of watchdog.py.

Assume all folder and file contents are present through git clone.

things to include:
pre-req installs
user and credential shuffling - disable pi user?
setup of logrotate
setup of service

[CuriousJames]

Don't disable pi, what I do now is disable passwords for ash and just use keys, but this shouldn't be handled by DIYAC, but we could include it as a recommendation on the readme
