Added $smf_user_info['smf_groups'] so you can check the SMF user groups in wp-side

Hi,

I'm using this plugin in Climbing club's website, and it's working really well. 

In our page we would like to be able to see what user-groups the user has, and limit some of the page functionality according to that. The easiest way seems to be this : )

Similar code can also be found from here:

So I guess that it's OK. At least it's working for us.
