Make IE 10 Install silent and do nothing if IE 10 is already installed

Hi Matt! I'm adding silent installer args to the IE install and letting chocolatey know that a 3010 exit code (reboot required) is a successful result. Unfortunately the install will always, as far as I have seen, cause the user to reboot before being able to run IE10 so I do include that messaging. The installer also does nothing in the event that IE10 is already installed.

I'm adding a VS 2013 package that requires IE10 and for now I'm shoving my own IE10 install into its Chocolatey Install. However if you accept this PR, I'd love to simply use this as a dependency.

Thanks!
