Pull #224

travis-ci

Recalculate position so it is based on the index of unicode code-points.

`cucumber-ruby` expects position values which are based on the index of the
code-point instead of the index of the byte. This change modifies the value
returned to `cucumber-ruby` before transmitting the resulting JSON over the
WireProtocol.

Prior to this change, the regex match's position (based on the match's position
in the byte array) would cause an `index out of string` error and crash
cucumber-ruby when pretty-printing the results of a test.

Closes #40.
