Updated docs based on user suggestions (#2196)

* Updated docs based on user suggestions

Thanks to @NeLLyMerC for the suggestions.  Removed the EOF syntax for creating a file.  Cleaned up the description of the systemctl commands.  Added 'sudo' to the journalctl commands as it will not show the logs if running as an unprived user.

* Update systemd.markdown

If the preceding command returns the string `systemd`, you are likely using `systemd`.
If you want Home Assistant to be launched automatically, an extra step is needed to setup `systemd`. You need a service file to control Home Assistant with `systemd`. If you are using a Raspberry Pi with Raspbian then replace the `[your user]` with `pi` otherwise use your user you want to run Home Assistant. `ExecStart` contains the path to `hass` and this may vary. Check with `whereis hass` for the location.
If you want Home Assistant to be launched automatically, an extra step is needed to setup `systemd`. A service file is needed to control Home Assistant with `systemd`. The template below should be created using a text editor. Note, root permissions via 'sudo' will likely be needed. The following should be noted to modify the template:
```bash
$ su -c 'cat <<EOF >> /etc/systemd/system/home-assistant@.service
+ `ExecStart` contains the path to `hass` and this may vary. Check with `whereis hass` for the location.
+ If running Home Assistant in a python virtual environment or a docker, please skip to section below.
+ For most systems, the file is `/etc/systemd/system/home-assistant@[your user].service` with [your user] replaced by the user account that Home Assistant will run as - normally `homeassistant`. For Ubuntu 16.04, the file is `/lib/systemd/system/home-assistant.service` and requires running this command `sudo ln -s /lib/systemd/system/home-assistant.service /etc/systemd/system/home-assistant.service` after file is created.
+ If unfamiliar with command line text editors, `sudo nano -w [filename]` can be used with `[filename]` replaced with the full path to the file. Ex. `sudo nano -w /etc/systemd/system/home-assistant@homeassistant.service`. After text entered, press CTRL-X then press Y to save and exit.

You need to reload `systemd` to make the daemon aware of the new configuration. Enable and launch Home Assistant after that.

```bash
$ sudo systemctl --system daemon-reload

To have Home Assistant start automatically at boot, enable the service.
```bash
$ sudo systemctl enable home-assistant@[your user]
```
To disable the automatic start, use this command.
```bash
$ sudo systemctl disable home-assistant@[your user]
```
To start Home Assistant now, use this command.
```bash
$ sudo systemctl start home-assistant@[your user]
```
If everything went well, `sudo systemctl start home-assistant@[your user]` should give you a positive feedback.
You can also substitute the `start` above with `stop` to stop Home Assistant, `restart` to restart Home Assistant, and 'status' to see a brief status report as seen below.
```bash
$ sudo systemctl status home-assistant@[your user] -l
