Move click2email_spec to click2mail_spec (remove "e")
Remove errant "puts" from BatchResponse
Fix click2mail_spec formatting and simplify description blocks.
Move click2mail_spec requires to spec_helper instead

Why: because then we won't have to include them in other *_spec files
written in the future.
Remove failing test for broken XML sent to Click2Mail

Why: it appears there API doesn't regard this broken XML as an error with
the job, so the status doesn't have any errors.  The test was errant in
expecting the response to have errors.
