0.5.1 Stablization Release

Version 0.5.1 of the P4 plugin for InteliJ community edition is now available. It includes internationalization of the exception error messages, and bug fixes.

• Internationalized the exception messages. Exceptions can be
  reported to the user, and so they need I18N support.
• Bug fixes
  • Not finding P4CONFIG in the hierarchy (#32)
  • Partial fix for incorrect parsing of P4Java API issue with fetching jobs (#33).
    This appears to be a server error during the returning of the job.
    An error is still reported to the user, but it is friendlier, and better
    details are logged.
  • Config "resolved values" should better reflect if it has been loaded (#34)
  • Reports of invalid configuration now better describe the source of the issue.
  • "Add file" while disconnected causes NPE (#35)
