Comment 2 for bug 1526163

Thanks, Billy.

I have pushed a new branch here:

http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/berick/lp1526163-webstaff-auto-renew

It includes a sign-off for Billy's code, plus a secondary commit:

==
Initiate the auto-renewal earlier in the checkout process, specifically before checkout response data is unnecessarily fleshed. Add an explicit auto_renew toggle to the checkout response blob to more clearly indicate why checkout counts are not modified.

Additional code comments and logging.
