added sequencer paths to bpath iterator, This needed to use get/set filename callbacks internally because the sequencer stores dir/file separately.

This means when moving large projects with many images/videos/sounds is possible with 'File, External Data, Find Missing Files'.
- needed so we can put peach animatic, glrenders & testrenders on the dvd.
also datatoc.c - brecht's fixes from apricot.
