COMMENTS
-users can now add comments to a database page.
-users can remove their comments from a database's page.
-added "databaseId" field to comments server model to assist in finding the right comments for a database
-removed "comments" array from database server model, as it was not used in my implementation

VIEW DATABASE PAGE

Database page will query for comments again instead of reloading window on comment creation/deletion.
Added reset comment field after submitting comment
-Accidentally deleted 'user' from DB model instead of 'comments'. This has been corrected.
-Changed findOne() function in usersController to call findAll/clean up portfolio as part of the GET success.
