[gephi-dev] Adding TAR.GZ archives support

[Sébastien Heymann]

@Mathieu

There is a big performance issue with archive files: they are uncompressed
twice. Once in ImportControllerImpl.java, and one in
DesktopImportControllerUI.java.

What about storing the reference to the uncompressed file inside the
FileImporter?
