adds support for params, x86 and force arguments

Hi guys,
Thanks for supporting chocolatey 0.9.8.24+. What a nightmare that was. I have a commit here which adds support for the params, x86 and force chocolatey arguments. Let me know what you think.

Thanks!
How do you see -force working? If a convergence is idempotent, how would force keep it from happening every time?
