Checkstyle report

[Nigel Daley]

A checkstyle report is now being generated as part of the Hadoop  
Nightly build.  This uses all the checkstyle rules in src/test/ 
checkstyle.xml

The report is linked from the "Build Artifacts" section of each  
build.  You can see the report linked from the latest build:
