Add some flexibility to I-feel-preTTY

Changed a few things

1. I made it default behavior to not add the trailing dots.
2. I allowed the function say() to take in no arguments, which will
   interpret it as a new line now (with same formatting as other
   output without putting the silly brackets).
Use PHP_EOL to be consistent
