Issue #362 - Updated media.html with things necessary for the simple comment feature

*   `media.html` now imports `wtforms.html` for use in comment form rendering
*   `media.html` now outputs a commenting form if `request.user` evals to `True`
*   `media.html` now outputs `MediaComments` if `comments` evals to `True`
*   `media.html` now includes `pagination.html` to handle comment pagination
