minor bug for the slides link that was in the base_admin template
added docstring for slides/controllers.py
added request from flask so i can get the POST data
adding slide with sqlalchemy works ok.
TODO need to add more support to read slides from db
added admin/get/slides endpoint so frontend can grab slides
