Add crazy (bad) xml parser thing

It only works for the Suunto "one xml file per dive" format, not for the
libdivecomputer one that just puts many dives in one file.

Maybe there is some way for libxml2 to handle concatenated xml files
(start again on errors), but I don't know it yet.

I need to get stinking drunk before I look at more xml mess.
