Added coding style tests using the "php-cs-fixer" tool. Simply run the "test/runTests.php" script from the project root and it'll run both the phpunit tests and let you know if you need to make any formatting changes. before your code will be accepted back into JShrink's mainline.
Added "php-cs-fxer" as a dev dependency and set it tun run in travis ci
Travis did not like the multiple script lines
Made wrapper test script for travis
Fixed formatting to stop triggering the testing errors on travis
Updated test wrapper for more readable output
