Mapper.xml not working on non-english log files

[sstair]

I modified the mapper.xml file as well (not that its actually an XML file :).

I changed it to support the european usage of a comma as decimal separator.
I also fixed it so that starting off with a "start new line" command, or putting consecutive "start new line" commands, is ignored.
Then I got rid of the "Using unitialized value" warnings.

It seemed to work for your french log file snippet from this post, tho you might want to try it on a larger sample.
