Omsipcreator breaks on whitespace chars in file name

[bitsgalore]

E.g. if an MD5 file contains sth like this:

693cea256b95802cd9442d07c9ad6cba Simple cd-rom.iso

Result:

IOError: [Errno 22] invalid mode ('rb') or filename: 'cdrom-cdaudio-dvdvideo-failed\\29c586b4-
edeb-11e6-9a83-00237d497a29\\"Simple'

Notes:

• checksum format is consistent with md5sum tool (doesn't use quote wrapping)
