Easy Code for Retrieving User Submissions 

The code for these methods was written out 4 or 5 times so I wrote a private method and gave it a parameter. I also added support for saved submissions.

*this was taken from the dev spec sheet on Reddit*

GET /user/username/where[ .json | .xml ]
→ /user/username/overview
→ /user/username/submitted
→ /user/username/comments
→ /user/username/liked
→ /user/username/disliked
→ /user/username/hidden
→ /user/username/saved
