Ogg Streams with Skeleton and Granulepos > 0 do not work(aka streams from mod_annodex)

right now gstreamer gets the offset wrong for ogg files or streams with skeleton stream. i.e. those coming from mod_annodex the problem is the first granulepos is seen as 0 instead of the offset. if you download or open this url in totem, totem starts playing at 0, displaying a still frame, while the video only starts playing at minute 42:21 http://pad.ma/v/Vuhet2t0.ogv?t=npt:0:42:21.000 <arkadini|pb> the problem is - it shouldn't treat skeleton streams as part of the conten

Fixes bug #530068.
looks like it still os not quite right, the basetime is just a delta which should be added to all timestamps the basegranule is just a hint about what was the granulepos of the page prior to the first page in the chopped stream the new patch removes the part that uses the base granulepos to calculate the offset. this should be only done with prestime / basetime.
