Hierarchical mode

[chris-y]

Experimental hierarchical mode has a few known issues:

• Archive requires entries for directories
• These directory entries need to be immediately ahead of their contents

Fixes for these:

• [ ] Fake directory entries
  • Attempted this but didn't really work, and definitely would have failed upon encountering a file suddenly two levels deep.
• [ ] Sort archive contents
  • Sort order needs fixing as a normal alphabetical sort (locale/Strncmp) puts dir.info between dir and the contents of dir (resulting in dir which is expandable but has no contents, and the contents either hidden or in a disconnected leaf state)
  • [x] xad v12 does not mark some directories as directories, instead they are files ending in '/'
  • I did fix this but have disabled it as it was causing other problems when I was testing under xad v13.

Previous commit attempts to sort '/' above all other characters, although I'm getting entries randomly sorted into the wrong places, so there is a bug in this function (beyond one I've already fixed).

Rethinking this. Might be better to scan the entire archive and work out the directory structure, rather than expecting the files to be in a sensible order. This will pick up when folders are implied.

Scan Create directory structure including files <-- this is the stage we're missing Move directory structure into list view
