Backup of your Lync 2013 script updated

Based on my own experience with this backup scripts, I have updated the persistent chat section

Instead of just running the "Export-CsPersistentChatData" command, it will now check to see if persistant chat is implemented at all.

I have done this to avoid the big blood red text you get if it is not implemented.

The script is signed, and should run on any server, unmodified.

Instead of sharing the script through Drop-box, I have posted it in the Technet Gallery, right here: Backupscript-Lync_2013_v3.ps1. It will give you an option to rate the script, or even discuss it.
