Feature request: step into jar/war/zip files

[lispercat]

Add the ability to step into an archive and see the content of it just like you would step into a folder.
To take it further, if you step into a file inside the archive unzip it on the fly and show the content.

Please look into archivemount. I do not think lf needs to add anything in addition to this.
