Re: mp3 seek issue I adjusted seeking for mp3 files. Now it will:
- seek VBR accurately and quickly, if there is TOC index in this file
- otherwise, seek file inaccurately and fast. For CBR files this will be accurate. For VBR without TOC this will be inaccurate the same way it was before (seek may result in incorrect elapsed time calculation)

I prefer speed over accuracy, as on mobile platform, seeking bad mp3 file accurately can take hundreds of ms and this is noticeable.
For most files it is speedy and accurate now (dev build 703).
