reenable if people complain
Fixed instagram (for now)
added support for chansluts
Added links to 4 new sites on main page
Hide old news; hopefully fix https recent rips bug
Fixed tumblr tags with hypens
Expanded imagebam to get paginated galleries
Added blank tumblr API key file to prevent crashes

People need to get a key, but the entire site should not crash if
they don't have a key yet.
