Add MINITEST_REPORTER env variable to override ENV detection

[brettwgreen]

• RubyMate, RubyMine, and TeamCity ENV detection overrides any specific reporter passed to use! method.
• Add a MINITEST_REPORTER env detection so users can override this detection and force usage of a specific reporter.
• Specific use case was attempting to use XML/JUnit style reports on TeamCity because of limitations of built-in Rake Runner step.
  • Rake Runner Build Step in TeamCity does a very poor job of choosing ruby versions automatically. Using a command-line runner for tests allows rvm to work as intended, and JUnit Reporter test output can be captured by TeamCity's XML Report Processing Build Feature.

Cool... I will pull into a few projects on my TeamCity setup and convert them over to try it out.

Thanks!
