Merge branch 'local-dev' into 'nc-21'

- Create a copy of the `ecloud_dev_example` directory locally where you want to install an `ecloud` development environment

- Use `cd` or file manager to enter the above directory

- Add a `.env` file with chosen attributes(example [.env](./ecloud_dev_example/.dev.env) file here, you can rename to `.env` to use same defaults)

- Set correct permissions to volumes:

  - `chown -R '33':'33' volumes/nextcloud/{html,data,log}`

- Pull the images and up the containers

  - `docker-compose pull`

  - `docker-compose up -d`

- Set config values, disable integrity check and refresh theme cache:

  - `docker exec -u www-data ecloud /var/www/html/occ config:system:set theme --value='eCloud'`

  - `docker exec -u www-data ecloud /var/www/html/occ config:system:set datadirectory --value='/var/www/data'`

  - `docker exec -u www-data ecloud /var/www/html/occ config:system:set logfile --value='/var/www/log/nextcloud.log'`

  - `docker exec -u www-data ecloud /var/www/html/occ config:system:set loglevel --value='2' --type=integer`

  - `docker exec -u www-data ecloud /var/www/html/occ config:system:set integrity.check.disabled --value='true' --type=boolean`

  - `docker exec -u www-data ecloud /var/www/html/occ app:enable integration_google`

  - To install more apps, use `docker exec -u www-data ecloud /var/www/html/occ app:install $app` where `$app` is the name of the app

- Add a new group in your bash shell to make the `html` folder editable(run commands with `sudo` if required):

  - `groupadd ecloud`

  - `usermod -a -G ecloud http`

  - `usermod -a -G ecloud $USER`

  - `chgrp -R ecloud volumes/nextcloud/html`

- To make the `html` folder editable to current user(`$USER`)(run commands with `sudo` if required):

  - `usermod -a -G '33' $USER`

  - `chmod -R g+w volumes/nextcloud/html`

  - Log out and log back into your system
