Changed the CAS Protocol! A 'yes' or 'no' first line followed with the user is still...

Now, the response has historical identifiers trailing the primary user, each on a new line.

Clients should check for each identifier...
-- if one is matched, use that username
-- if two are matched, merge accounts on client end
-- if none are matched, create a new user with primary username

Old protocol response:
yes
foobar123

New protocol response:
yes
foobar123
barbaz345
barfoo789
