Making state lzop compatible

### Problem

The states aren't lzop compatible

This is a problem because they can't be extracted

	lzop --info RSPE01.s08
	lzop: rspe01.s08: not a lzop file

Inspecting the state is benecifial f.e. when creating [binary patches](http://www.supermodel3.com/Forum/viewtopic.php?t=118)

### Solution

Making the state lzop compatible because

* that allow extracting the state

This patch shouldn't be merged until these changes are made

* use liblzop instead

Save the state header values in the lzop header

* time in mtime
* ISO id in filename
