add multisession capabilities to Brasero Nautilus extension

by Alexey Putilov for GNOME

At work with the computer an integral part is work with files so and with the file manager. To user work with files and the information is important, for it has no value where this information is placed. Therefore it is important to provide uniform interaction of the user with the information located anywhere. The purpose of my project is granting to the user of such transparent work with the files which are on optical disks just as if work passed with a hard disk.
