Lync for mac removal script

Hello all,
   Here's a little script that cleans out Lync for mac from OS X, this has been tested on 10.8 and 10.7 and found to be working very well, this basically automates the steps listed here:

                                                                                                                                                                                                                  Run the script by pasting it into a text editor, saving it as .sh and then making it executable by chmod +x lync_removal.sh, run it using: sh lync_removal.sh from the terminal.
This works silently so there won't be any popup window at all.
I am still working on removing keychain entries for Lync, but have found no way of doing this without serious risk on nuking the keychain.
