Patch for updated documentation / properties for the maven-pmd-plugin.

• Fixed how-to to remove reference to driver.properties, per the
  recommendation from MAVEN-287.
• Removed ${plugin-resources}/rulesets/*.xml files, as they are built
  into the pmd.jar file and don't need to be extracted from the pmd
  plugin to work.
• Cleaned up how-to documentation.
• Changed How-To to faq format to allow maven-faq-plugin to handle the
  this documentation.
• Changed the navigation.xml to point to the generated faq and
  new links to point to the maven / ant / pmd pages.
• Cleaned up About/Frontpage documentation.
• Cleaned up <reports> section to exclude unused reports such as
  jdepend, javadoc, pmd, checkstyle, etc.. (we don't have any java
  source files to make those reports work anyway.)
• Added myself as a contributor to the project.xml.
• Updated project.xml to point to new pmd-1.3.jar

[NOTE] This jar file would need to be uploaded to the repository
first in order to support this change, as pmd-1.2.1.jar is the most
recent found in the maven repository.
See MAVEN-1021 (request to upload pmd 1.3)
