Features/reddit and dto (#2)

* updated db calls to new endpoints.  Not all are finished yet

* updated models to use the new dto objects to hide orm values

* updated reddit to build articles based on what type of post it is

* getting reddit ready to post the articles to the db

* Now able to post to the db under the new DTO object

* moved the reddit model to articles model to the struct and out of main
