Dork checking fix and first argument is dork.
Simpler example, urlencoding dork.

A shorter example in usage text and urlencoding user-supplied dork to
avoid 'bad-request' response from Google. (For eg; if dork contains
spaces)
urldecode + terminal encoding issue.

Decoding urls for writing to file and displaying title/summary as raw.
Some titles/summaries may contain code that the terminal is not capable
of displaying (For eg; UTF in cmd).
Just some comments.

Displaying HTML/checking for regex switches.
goo_writer

goo_writer will handle file outputs, instead of goo_operator
