Updated to 0.1.0 - Rewrote line splitting

I updated the tests with some tests derived from PHP's unit tests for
their own quoted printable function. However, the PHP tests didn't meet
my expectations (ie. they were wrong) nor the Perl implementation. So, I
took the PHP tests, but decided to trust the output from the Perl
implementation of encode quoted printable.

I rewrote the line splitting from a regular expression to a more
readable function.
