Dragon Player adds analyzer

[Ian Monroe]

So I added the Phonon audio analyzer that Martin worked on for his
GSoC last summer. Its mxcl's old-school block analyzer from Amarok
1.4. Its not in the main window of the program like it was for
Codeine, but only displays when playing an audio-only file. This is
partly because I don't really trust backend support for this stuff.
But maybe this will give some more incentive for the backend devs to
work on this. :)
