Sickchill: Ubuntu installation instructions

[Zw3rv3r]

Because of the name change to SickChill the Ubuntu installation instructions (https://github.com/SickChill/SickChill/wiki/SickChill-installation-Ubuntu-15) do not work correctly.

The daemon script references to the group/user/folder have changed but the documentation for creating group/user/folder required for the script to run hasn't changed yet.

I successfully installed and restored SickChill with these changes:

step 2:
sudo addgroup --system sickchill
sudo adduser --disabled-password --system --home /var/lib/sickchill --gecos "SickChill" --ingroup sickchill sickchill

step 3:
sudo mkdir /opt/sickchill && sudo chown sickchill:sickchill /opt/sickchill
sudo -u sickchill git clone https://github.com/SickChill/SickChill.git /opt/sickchill

In the following steps "sickrage" could also be changed to "sickchill", recommended but not necessary to get everything working.

I have edited the Wiki page in order to reflect the changes and - hopefully - avoid problems for other users.

If it's fine, I think this might be marked as closed.

Changed a small typo yesterday (didn't know I was able to edit that page) but I used it in Ubuntu 18.04 LTS and it worked fine.

I mass edited wiki pages right now, hopefully it is good now.
If you find broken links/info please let me know.

There is a small typo in the instructions:
https://github.com/SickChill/SickChill/wiki/SickChill-installation-Ubuntu-15

sudo adduser --disabled-password --system --home /var/lib/sickchill--gecos "SickChill" --ingroup sickchill sickchill

^^ it is missing a space after sickchill .. therefor it fails to add the user
