Listing buddygroups

I needed to list out buddygroups in the contacts tab so here's my code - it just does what it needs to do and so may need some extra stuff to fit into coding standards etc. but thought it might be of use to someone as couldn't find a solution for it myself.

The result is something like this:

* Group
* Group1Name (Group1Member1name, Group1Member2name)
* Group2Name (This group has no members!)
* Group3Name (Group3Member1name)
* Contact
{continues as per current contact tab}

So one selects buddylist groups just as one would contacts, and it inserts the names as if you were to select multiple single names.
