Announcement: mafw-gst-eq-renderer initial version

Hi maemoers!

After reading some complaints about lack of an equalizer in N900, I've
written a replacement for mafw-gst-renderer called mafw-gst-eq-renderer.
It is not part of official MAFW.

Roughly speaking, it is mafw-gst-renderer with a gstreamer's 10-band
equalizer.

There are two flavours: one intended to replace current
mafw-gst-renderer, and another one intended to coexist with the original
renderer.

If you choose the second flavour, default mediaplayer will not be able
to use it, as it only handles one renderer: mafw-gst-renderer.

Both flavours come with a Control Panel applet that allows to set
equalizer values, and with a set of typical presets (though you can save
your own presets).

More information here:

Which is the reason? If you control equalization with the applet, why
can't you use it with the official mp?

Because official renderer doesn't include an equalizer element in
gstreamer pipeline, which fork does.

The fork sets equalizer values from gconf. And applet is intended to
change those values in gconf, though you can write your own utility to
do it.

But if the change is only inside the renderer, I don't see any reason
why it couldn't work with the official mp, as they don't care anything
about the pipeline.

MTR flavour creates a new source with its own uuid (gsteqrenderer),
which Mediaplayer doesn't handle.

MGR flavour replaces mafw-gst-renderer, reusing the same uuid
(gstrenderer), which is handle by mediaplayer.

So if you want to use it with mediaplayer, you must install MGR flavour
and remove old mafw-gst-renderer (to avoid conflicts as both are using
the same names).
