Version Ruleset Update: Generic Version Check

- Removing slf4j specific version handling

- Adding a global version check that will exclude any version that does
  not include the maven plugin version scheme (EG ending with -M7), but
  does contain upper or lower case letters and optional following
  digits.

  Based on current version strategies of project dependencies and
  plugins, this should enforce only updating to known release-quality
  versions.
