Reworked prototype extensions, moved tumblrising url functionity into prototype extension
Selectively enable features, script include reorg

 * Added loadNew functionality button, implementation in later commit
 * Display tumblr user avatars
 * Add anchor on timestamps to single_post page for post
sortBy was hidden behind a feature flag, added all function as per python

 * Mended mend_url functionality
Added avatar_url CP, tumblrized CP

 * avatar_url amounts to a simple Em.String.fmt call
 * tumblrized CP returns and object with a tumblrized version of every string property on the model
Added loadNew backing code

 * Some cleanup of silly code
 * Make sure to get the posts in the right order
 * Make sure to use the query from up above... this frame on the callstack
Now that we have bandwidth and can subsequently afford it...
Play pass the parcel with the error obj, correct wording, add empty headers
In the right order, if you would be so kind
Add the api_key to the query only if we're not authenticated some other way
Updated EmberJS && Ember Data
Assertain authenticated status correctly, correctly reference the namespace
