This change adds support for the PMD static analyzer (which is mostly
java-focused). There are two configurable fields: the path to the executable
(which is needed because PMD doesn't really have a good, standard
installation), and the list of rulesets to run.

  • Posted a big java change and saw that PMD ran and reported the results
    successfully.
  • Misconfigured the PMD path and saw that the resulting error was reported
    correctly.
