GaudiConf:add "light" version of dst-dump script from Bender

GaudiConf:

• add light version of dst-dump script from Bender
• some functionality can't be ported in an easy way, in particular, access to grid files, LFN -> PFN conversion, automatic setting of DDDB/CondDB-tags, etc... But probably it is ok.

I've not tested it for all data types, but it looks OK for several test files.
