Improving SSL documentation (Mono / Linux)

I just added successfully SSL support to my personnal sonarr instance.

Following the documentation was not enough for me because the documentation did not inform that the httpcfg command must be run under the same user than the user running mono.

I just added the comment markus101 gived on the forum

Mentionned by markus101 there :
(Mono didn't support intermediate SSL certificate chains causing problems between nzbToMedia and NzbDrone/Sonarr [fix])

“make sure its run by the user that will be running mono.”

You can fine my modified wiki page there :

Be free to edit the layout / my english spelling…
