meetup checkins

added meetup.com checkins api so that on days that we have meetups, once
a member checks in, they're icon from meetup will display on index,
under the button in ".carousel-caption".
CNAME and Tooltips

changed CNAME from codeforhamptonroads.org so GitHub doesn't send me an
error after each commit.
Bootstrap tooltips added: tooltips displaying the member's name now
working when members check-in at meetups.
CNAME

after looking up CNAME i think changing it will only fix my github
error, and pass it along to the brigade's repo. so i'll deal for now.
