GES 1.12, Two bugs (possibly related) with (1) GESEffect volume and (2) layer ordering priority

[David Ing]

Thibault, your suggestion for #1 worked like a charm.  It fixed both of the
problems.

I have two followup questions.

   1. This experience has me a little worried.  If GESEffect does not work
   well for the `volume` plugin, can I expect problems with most of the other
   plugins?
   2. For future reference, I don't know how to save a *.xges file.  Would
   I use `ges_timeline_save_to_uri` for that?
