[Slapt-get-user] Add function like apt-file

[Georg Nagel]

Hi all,
i like to see an option to search for files in tgz's
You could use the MANIFEST(.gz|.bz2)? files for that. For example 
Linuxpackages mirrors got these files
Im not into C/C++ so i cant make a patch or something :(
Hop its realizable (does this word exists ? :))

Best regards
Georg Nagel
