Switched everything over to use can.* functions from telescope-lib instead of using can* functions from lib/permissions.js, deleted lib/permissions.js, added some tests for permissions, and some other random cleanup like deleting unused code.
Conflicts:
client/views/comments/comment_form.js
Using {{pathFor}}, path(), and url() where possible. Passing in path
to Meteor.absoluteUrl() where the IronRouter functions didn't make sense.
Also deleting some random unused code.
