A little more on internationalization...

A few small bug-fixes. A little more documentation about how to provide translations for the tool.

The most annoying bug fixed was one that attempted to find gaps cross-analysis when there was only one namespace being used. It resulted in an extremely unhelpful statistic which now won't appear for single tool analyses.

Enjoy!
