Buy Into Secondary Usergroup

[ZiNgA BuRgA]

This is a quick modification to the Buy Into Usergroup Module.

Instead of changing one's primary usergroup, this one causes the user to join the group as a secondary usergroup.

This allows users to buy access into private forums, without causing any other side effects, for example.

EDIT: Updated to v1.0.1

Updated to v1.0.1.

Like the Buy Into Usergroup update, this adds time limits for usergroups.

I think this is especially useful, especially for secondary usergroups.

For example, a user could pay to access "Premium Content" for 14 days, after which, they'd have to pay again to access it.
