Add loop option to pixbuf producer

[xaiki]

We use the pixbuf producer to show our tv channel's logo, but only want it to spin once per block,
hence this simple patch to add a 'loop' option to our .mlt.

example use:

  <filter>
    <property name="mlt_service">watermark</property>
    <property name="resource">/srv/Mosca/LOGO_WALLKINTUNTV_%05d.png</property>
    <property name="composite.geometry"> 70%/20%:20%x20%</property>
    <property name="producer.loop">1</property>
  </filter>

I am not certain what value this provides. The pixbuf looping can already be controlled simply by adjusting the length of the producer. If you want to loop once and then hold, then you can use 2 watermark filters with in/out set appropriately: one that loops and another that displays a single image.

the value is: simplicity,

I'd rather have this automatically sorted out by this trivial patch than having to re-write the .mlt if the artists adds a frame to the animation (or have to write code arround this to bloat my .mlt). (that way I can just tell art to drop the logo in a folder and everything updates auto-magically).
