ANN: xmls 1.0 release

This has been ready for a while but a few have reported bugs that are 
now fixed in the current version so I thought I might has well release it.

This is mainly a bugfix release.  The only notable new feature is that 
xmls now optionally outputs indented xml text from it's toxml function.

Code and changelog are available here:
