fixed get_descendants

[fedorareis]

Currently get_descendants only returns itself. I made get_desendants behave more like get_tree_members which means it now returns all groups that are lower on the tree than the parent.

One other thing to note is that I also swapped out the search for get_children. The new search means the result list no longer needs to be built manually, let me know what your thoughts are on that change. I can revert it to the previous method or I can go through and update all of the functions to use the new search method.
