project_issue_file_review 6.x-2.8-rc1

New in this version:
- Modified how pifr_server checks to ensure it has a result for all environments (should address at least one source of invalid failed=>@reason false negatives)
- Ensured that testbots do not clear their PIFT_TEST variable until after the send_response xmlrpc communication completes (should address one source of testbot reconfirmation failures)
- Support the D8 'langcode' install argument to allow for removal of 'testbot compatibility' code in Drupal 8.
- Fixed plurality in results summary messages.
- Added testbot ID and review timestamp to the review log
- Support for test files located in directories other than module root and /tests
- Check for empty --file argument on run-tests.sh before executing, to handle certain '0 tests passed' scenarios
- Only list relevant test cases in the review log, instead of all core test cases
- Fixed two 'undefined index' errors appearing in the watchdog logs
- Removed two call time pass-by-reference instances
- Exclude external (third-party) files from core coder review results
