This reverts commit c61e84bc, reversing
changes made to b88899ff.

modified app to return a hash if current_user is not present; removed view specs in postsController specs & moved logic to js/jasmine

remove sort order logic from controllers; backbone stream does not support it; was to be depricated anyway

added api response for likes; cleaned up view logic; specify like collection url from parent model (Post)

migrating like actions over to backbone; some cleanup; bump jquery to
1.7.1

DG DH; made acts_as_api play nice with backbonejs.  comments are semi-functional; stream elements use the StreamElement js widget (for now).

add acts_as_api to the models directly for now.  the 'root node' problem (posts : {}) breaks backbone.  wip

this should fix a weired test polution case on travis where the x-git-revision header is suddenly nil

This reverts commit 64081059.

Conflicts:

	db/schema.rb

we find a better way to reimpliment it in a  more sane way
