update brasero to 2.26.3
changes: minor bugfixes, translation updates

pkgsrc changes:
-in scsi io code, remove the code which builds a raw device path
from a block device - use the raw_device hal property instead
-split out the nautilus plugin, allows to use brasero (and its
clients, eg sound-juicer) with less gnome desktop overhead
-support playlist parsing as an option -- unfortunately this
pulls in evolution-data-server indirectly which is pretty large
for that limited gain of functionality (on per default, as in
other pkgs able to use the evolution database)
-cleanup
