Save the world tonight...
This is all rather frustrating
Lots of work, see message;

add hollow worker
made ajax.MappingStatusHandler work with tornado
transitioned to pure api key based auth; oauth not needed
fixed debug.py to work with tornado
made it possible to use non-tumblr urls - in theory
more or less re-wrote the test sink path follower
added mocks for taskqueue and memcache
removed unneeded memory usage from process_graph_data resulting from resolving generators
simplified compute_d3_points
added utilies for determining whether a url is a tumblr username or full url, and modifying as needed
moved graph represention functions into utils.py, where they belong >.>
cleaned up in general
