libobs: Change groups to actual public types

Browse Source 
(This commit also modifies UI)

Changes groups to their own independent type, "group".  This allows them
to be used like other regular types, and allows the ability to reference
groups in multiple scenes.  Before, a group would always be linked to
the scene it was in.  This made it cumbersome for users to modify groups
if they had a similar group in multiple scenes (they would have to
modify each group in each scene).  Making groups like other source types
makes more sense to solve this issue so they can be referenced in
multiple scenes at once.  This also removes a significant amount of
group-specific handling code required for implementing groups in the
front-end.

One limitation however: due to the way sub-items of groups are
seamlessly modifiable and sortable as part of the whole scene, the user
cannot have multiple references to the same group within one scene.
