bunch of renaming to accommodate testing multiple outputFormats
these aren't needed since trim was added in the test output reader
updated docs to mention multiple output formats
bunch of refactoring, or something... i don't remember, but it works now
added plurals & made outputFormats into an array... for everything
passing a string can actually return a different output than a file, sometimes
refactoring test for it to be able to check all output formats
removed console.log
moved options to mocha.opts file & added lower slow check 'cause transformers should be really fast
switched to _.clone since it's required anyway
