[patch] Refresh previews on branch toggle?

[Scott Kostyshak]

Attached is a patch that refreshes previews whenever the user activates
or deactivates a branch. The motivation for this patch is that if a
child document is previewed in the master document, and if the child
document has the branch inside it as well, the preview will be incorrect
when the branch is toggled (without this patch).

However, this patch will cause all previews to refresh. I'm concerned
that the inefficiency is not worth the benefit. Any thoughts on this
patch and any thoughts on an ideal solution? For example, would
removePreviews() and updatePreviews() ideally have arguments that allow
to specify which type of previews to update?
