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!
Hi,
I can remove support for the -force parameter if you wish. 

By the way have you noticed that the :upgrade action and using the :install action with a version number specified also run every time?
