Fix build error due to forward enum declaration

In full build, the following error happens. So fix it by including the
definition file before the forward declaration one.

```

Fix T79121: Dependency cycle when driver points to prop with 'scale' in name

This makes `RNANodeQuery::construct_node_identifier()` more strict in
its matching of certain property names.

The downside of this approach is that it's not possible any more to use
`"rotation"` and expect a match for `"rotation_euler"` and friends, so
the list of strings to test against is now 3x as long.

UI: Show message in transform panel when no metaball elements are selected

The complete lack of a transform panel was confusing enough to spawn
this question: https://blender.stackexchange.com/q/169074/599
Displaying a message instead of nothing is more consistent with the
behavior of the mesh transform panel anyway.
