Added ownCloud to the PI

My very own raspberry cloud!

Since this website has been running for quite a while now, I felt it was time to try and add ownCloud to this one PI and see how that performs.

I’m especially interested in how mariadb performs in combination with the heavy database load that ownCloud usually causes when uploading many files.

Also, i think it is a good auto-backup function to have for my andriod smart-phone and my wife’s.
