Title: Added support for Elavon's commands:

CCVERIFY
CCADDRECURRING
CCMODIFYRECURRING
CCDELETERECURRING

Tests were also added. Unit tests pass correctly. Remote tests were working until Elavon turned off my access to their test env. Code using these changes is in use in a production environment, however (except for CCMODIFYRECURRING).
