Checkstyle:
1) wired checkstyle into the build (for verify)
2) suppressed all modules except fcrepo-audit, for the time being
3) modified trailing whitespace rule to allow trailing whitespace on lines with only a "*" (e.g. javadoc lines)

Eclipse code formatting cleanup:
1) fedora-formatter.xml incorrectly specified tabs instead of spaces
2) added fedora.importorder
