Bug 23346: Add without-db-name parameter to koha-dump

Bug 23346: Add without-db-name parameter to koha-dump

Test plan:
Run koha-dump [yourdb]. Rename the files in var/spool/koha/[yourdb]
Run koha-dump --without-db-name [yourdb]
Run a diff between the unzipped sql files. The last dump should not
contain a CREATE DATABASE and USE statement. See BZ 15664 c4.
