Changed function form of calcMD5
Removed the variable "sixteen" from md5.js and sha256.js
Refactored out the add function from md5.js and sha256.js, put a few "strategically placed" |0's. Passes all tests in test.js
Bit of whitespace to make my linter happy
Merge remote-tracking branch 'heavensrevenge/master'
Compile @heavensrevenge's changes (yay bytes!); also add some whitespace

I've decided I like whitespace now.
