Enhancement request..xz support.

Add support to the pack/unpack plugin for the .xz file extension.

It is based on the lzma sdk and actually uses lzma2 for compression
within an xz wrapper.

I've added it to filetypes and can unpack without issues but I ran
into a roadblock trying to modify the plugin code to support xz.
