Support paste between automation lanes.

Also push the increasingly unwieldly paste parameters into a context object.

As with othe things, currently it is only possible to do "cross-type paste" by
explicitly selecting the target track.  We will need to get automation region
view selection working to do better here, but at least for now it's possible to
get the data over.
