Support Copy To Selected and Alt-Click for F-Curves in the curve editor.

This affects the curve display color setting, but is really intended
for future per-curve options.

The id_data reference in the created rna pointers refers to the object
even if the curve is actually owned by its action, which is somewhat
inconsistent, but the same problem can be found in existing code.
Fixing it requires changes in animdata filter API.
