Add a plugin API method for setting the content of a popup

The PluginApi offers `popup()` to be called without a `moduleName`
argument. That only makes sense if the caller has the ability to set
the content of the popup by other means.

This change adds a `appendContent()` method to the popup API.

This was triggered by working on the automerger plugin, which currently
has to rely on the private `_getElement()` method.
