Fixed breakage caused by splitting on SPACE in OPENVPN_CONFIG

Browse Source 
Changed to split on comma as many openvpn configs have space in the name.

Added a bit more validation that a provider is set.

Updated docs.

You can also provide a list of openvpn configuration filenames separated by a space.
You can also provide a comma separated list of openvpn configuration filenames.
If you provide a list, a file will be randomly chosen in the list, this is useful for redundancy setups. For example:
```
-e "OPENVPN_CONFIG=ipvanish-AT-Vienna-vie-c02 ipvanish-FR-Paris-par-a01 ipvanish-DE-Frankfurt-fra-a01"
-e "OPENVPN_CONFIG=ipvanish-AT-Vienna-vie-c02,ipvanish-FR-Paris-par-a01,ipvanish-DE-Frankfurt-fra-a01"
```
If you provide a list and the selected server goes down, after the value of ping-timeout the container will be restarted and a server will be randomly chosen, note that the faulty server can be chosen again, if this should occur, the container will be restarted again until a working server is selected.
