Uninstalling non-admin install of Google Chrome (Part II)

So my earlier attempt at uninstalling per-user / non-admin install of Google Chrome worked, but Google Updater was re-installing it daily.  So I re-wrote it in PowerShell mostly because I'm finally taking the plunge to learn it.  If you're using SCCM 2012 as I am, deploy the .bat file and use it as the command line.  It'll make sure execution policy doesn't get in your way.

--NOTE: I have NOT tested the MSI unistaller portion yet.  This is the way I imagine it'll work (get the uninstall string from the registry & run it, sounds simple).  But I haven't pulled doen the MSI and tested it yet.  When I do I'll update this section saying it's tested.
